Identify the loop construct:
- A.
If-else
- B.
Goto
- C.
While
- D.
Switch-case
Correct Answer
C. WhileExplanation
The loop construct identified in this question is "while". The "while" loop is used to repeatedly execute a block of code as long as a specified condition is true. It checks the condition before executing the code, and if the condition is true, it continues to execute the code block. Once the condition becomes false, the loop terminates and the program continues with the next line of code after the loop.Rate this question:

Which of the following is not a storage class
- A.
External
- B.
Automatic
- C.
Register
- D.
Define
Correct Answer
D. DefineExplanation
The storage classes in C programming language define the scope and lifetime of variables. The "define" option mentioned in the question is not a storage class. In C, "define" is used to create a macro or a constant value using the preprocessor directive #define. It does not deal with the scope or lifetime of variables like the storage classes do.Rate this question:

Which of the following is a correct way of defining a symbolic constant pie in C
- A.
# define pie = 22/7
- B.
#define pie 22/7
- C.
#define pie= 3.142
- D.
# Define pie 22/7
Correct Answer
B. #define pie 22/7Explanation
The correct way of defining a symbolic constant "pie" in C is by using the "#define" preprocessor directive followed by the name of the constant "pie" and its value "22/7". This creates a symbolic constant called "pie" with the value of the mathematical constant pi (approximately 3.142).Rate this question:

In switch statement
- A.
More than one default allowesd
- B.
Default case, if used, should be the last case
- C.
Default case, if used, can be placed anywhere
- D.
Default case must be present
Correct Answer
C. Default case, if used, can be placed anywhereExplanation
In a switch statement, if a default case is used, it can be placed anywhere within the switch statement. This means that it doesn't necessarily have to be the last case. The default case is executed when none of the other cases match the value being switched on. So, if the default case is placed before other cases, it will be executed if none of those cases match.Rate this question:

- A.
2
- B.
3
- C.
Any number
- D.
1
Correct Answer
C. Any numberExplanation
In a do...while loop, the condition is checked after the loop is executed. This means that the loop will always execute at least once. After each iteration, the condition is checked, and if it is true, the loop will continue. Therefore, there can be any number of while statements in a do...while loop, depending on the condition.Rate this question:

The storage area for register variables
- A.
Cache
- B.
Memory
- C.
Processor registers
- D.
Virtual memory
Correct Answer
C. Processor registersExplanation
Processor registers are small, high-speed storage areas located within the CPU. They are used to store data that is frequently accessed by the processor, such as variables and intermediate results of calculations. Register variables are stored directly in these registers, providing fast access and improving the overall performance of the program. This is why the storage area for register variables is referred to as processor registers.Rate this question:

- D.
The initialization part of a for statement cannot have more than one initialization
Correct Answer
D. The initialization part of a for statement cannot have more than one initializationExplanation
The initialization part of a for statement can have more than one initialization. In a for statement, the initialization part allows us to initialize multiple variables or perform multiple initialization operations using commas. Therefore, it is possible to have more than one initialization in the initialization part of a for statement.Rate this question:

The global variable can be declared
- A.
After main
- B.
After block
- C.
Before main
- D.
Within block
Correct Answer
C. Before mainExplanation
Global variables can be declared before the main function in C programming. This means that the variable can be defined outside of any function, including the main function, and can be accessed and used by any function within the program. Declaring a variable before the main function allows it to have a global scope, meaning it can be accessed from anywhere in the program. This is useful when a variable needs to be shared and used by multiple functions.Rate this question:

- D.
Dowhile loop is ececuted only if the condition is true
Correct Answer
A. While loop is executed atleast onceExplanation
The explanation for the given correct answer is that a while loop is not executed at least once. This is because the while loop checks the condition before executing the code inside the loop. If the condition is initially false, the code inside the loop will not be executed at all.Rate this question:

printf (“\ “ well done\” ”); what will be the output of this statement
- A.
\“well done \”
- B.
Well done
- C.
“ well done”
- D.
\ well done \
Correct Answer
C. “ well done”Explanation
The given code snippet is using the printf function to print the string "\ " well done\" ". However, the backslash character "\" is an escape character in C programming, so it is used to escape the following character. In this case, the backslash before the double quotes is escaping the double quotes, so the output will be " well done" with a space before the "well done" string.Rate this question:

- D.
Compilation error
Correct Answer
A. 0Explanation
The program declares a static variable 'y' but does not initialize it. In C, static variables are automatically initialized to 0. Therefore, when the program prints the value of 'y', it will output 0.Rate this question:

The number of elements in array declaration
- A.
Dynamically identifies based on largest index used in program
- B.
Does not require to be specified
- C.
Assume default size as ‘0’
- D.
Requires to be specified
Correct Answer
D. Requires to be specifiedExplanation
In array declaration, the number of elements usually needs to be specified. This is because the compiler needs to allocate memory for the array based on the specified size. If the size is not specified, the compiler will not know how much memory to allocate, leading to potential errors or unexpected behavior. Therefore, it is necessary to specify the number of elements in the array declaration.Rate this question:

In C every variable has
- A.
A type and size
- B.
A type, name, value and size
- C.
A name and type
- D.
A size and value
Correct Answer
B. A type, name, value and sizeExplanation
In C, every variable has a type, name, value, and size. The type determines the kind of data that the variable can hold, such as integer, float, or character. The name is the identifier used to refer to the variable in the program. The value is the actual data stored in the variable. The size represents the amount of memory allocated to store the variable, which depends on its type. Having a type, name, value, and size for each variable is essential for proper memory allocation and data manipulation in the C programming language.Rate this question:

All the elements in the array must be
- A.
Defined
- B.
Neither initialized nor defined
- C.
Initialized and defined
- D.
Initialized
Correct Answer
A. DefinedExplanation
The correct answer is "defined" because in order to use elements in an array, they must be defined, meaning that they have been declared and given a value. Initialization is not necessary, as the elements can be assigned values later on. However, they must be defined before they can be used in any operations or calculations.Rate this question:

How many bytes will be allotted for the declaration int num[4] [3]
- A.
6 bytes
- B.
24 bytes
- C.
12 bytes
- D.
48 bytes
Correct Answer
B. 24 bytesExplanation
The declaration "int num[4][3]" creates a 2-dimensional array with 4 rows and 3 columns. Each element of this array is an integer, which typically requires 4 bytes of memory. Since there are a total of 4*3=12 elements in the array, the total memory allotted will be 12*4=48 bytes. Therefore, the correct answer is 24 bytes.Rate this question:

If statement is a —————statement
- A.
Loop construct
- B.
Two way decision
- C.
Multiway decision
- D.
One-way decision
Correct Answer
D. One-way decisionExplanation
A one-way decision statement is a type of programming statement that allows for the execution of a block of code only if a certain condition is true. It does not provide any alternative paths or options for the code execution. In other words, it allows for a single path of execution based on the condition being true or false. This is different from other types of decision statements such as two-way or multiway decision statements, which provide multiple paths or options for code execution based on different conditions.Rate this question:

- A.
Sizeof (datatype) * 2
- B.
Size of (datatype) * size of used array elements
- C.
Sizeof (datatype) * sizeof array
- D.
Size of (array) * datatype
Correct Answer
C. Sizeof (datatype) * sizeof arrayExplanation
The correct answer is "sizeof (datatype) * sizeof array". This is because the size of the array is determined by multiplying the size of each element (datatype) by the total number of elements in the array (sizeof array). This calculation gives the total memory required for the array.Rate this question:

- A.
None of the element are initialized to zero
- B.
Only first row elements are initialized to zero
- C.
Only last row elements are initialized to zero
- D.
All the array elements are initialized to zero
Correct Answer
D. All the array elements are initialized to zeroExplanation
The given statement initializes a 2-dimensional array called "table" with 2 rows and 3 columns. The initialization values are provided within double curly brackets. In this case, the elements are initialized to zero. Since no specific values are assigned to any element, all the elements in the array are initialized to zero.Rate this question:

- C.
For(a=‘a’; a
- D.
For(a=’A’ a
Correct Answer
D. For(a=’A’ aExplanation
This statement `for(a=’A’ a` is the correct answer because it initializes the variable `a` with the character 'A' and loops through the character set from A to Z. The loop will continue as long as `a` is less than or equal to 'Z'.Rate this question:

The amount of storage required for holding elements of the array depends on
- A.
Data type
- B.
Datatype and size
- C.
Run-time requirement
- D.
Size
Correct Answer
B. Datatype and sizeExplanation
The amount of storage required for holding elements of the array depends on the data type and size. Different data types have different sizes in memory, and the size of the array also affects the total storage required. For example, an array of integers will require more storage than an array of characters because integers typically have a larger size in memory. Similarly, a larger array will require more storage than a smaller array, regardless of the data type. Therefore, both the data type and size of the array are important factors in determining the amount of storage required.Rate this question:

If we don’t initialize a static array, what will be the elements set to:
- A.
Character constant
- B.
A floating point number
- C.
0
- D.
An undetermined value
Correct Answer
D. An undetermined valueExplanation
If we don't initialize a static array, the elements will be set to an undetermined value. This means that the values of the elements in the array will be unpredictable and could be any random value that happens to be stored in memory at that time. Therefore, it is important to always initialize static arrays to avoid accessing and using undefined values.Rate this question:

Char array cannot be printed directly using printf
- B.
Array is not a left value and so cannot be assigned to
- C.
Program compiles without error, but prints an unpredictable value
- D.
Array cannot be initialized as above
Correct Answer
D. Array cannot be initialized as aboveExplanation
The given program is trying to assign the value of one character array (m1) to another character array (m2) using the assignment operator (=). However, in C, arrays cannot be assigned directly. Instead, each element of the array needs to be copied individually. Therefore, the program is incorrect because it is trying to assign the entire array m1 to m2, which is not allowed.Rate this question:

- D.
0
Correct Answer
C. 45Explanation
The program initializes an integer variable 'a' and sets it to 0. It also initializes an integer variable 'b' and sets it to 0. It then creates an integer array 'c' with 10 elements and assigns the values 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 to the elements respectively.
Next, a for loop is used to iterate through the array 'c' and add each element to 'b'. After the loop, the value of 'b' is printed.
Since 'b' is initialized to 0 and each element of 'c' is added to it in the loop, the final value of 'b' is the sum of all the elements in 'c', which is 45.Rate this question:

Dynamic memory allocation in array results in
- A.
Allocation of memory at debugging time
- B.
Allocation of memory at file saving time
- C.
Allocation of memory at compile time
- D.
Allocation of memory at runtime
Correct Answer
D. Allocation of memory at runtimeExplanation
Dynamic memory allocation in array allows for the allocation of memory at runtime. This means that the memory is allocated during the execution of the program, allowing for flexibility in the amount of memory needed. Unlike static memory allocation, which occurs at compile time, dynamic memory allocation allows for the allocation and deallocation of memory as needed during program execution. This is particularly useful when the size of the array is not known beforehand or may change during runtime.Rate this question:

- B.
Prog
- C.
Program
- D.

Correct Answer
B. ProgExplanation
The program declares a character array named "name" with a size of 5. It then uses the scanf function to read a string input and store it in the "name" array. Since the array can only hold 5 characters, any input longer than that will result in a buffer overflow. In this case, the input "Program" has 7 characters, so only the first 4 characters "Prog" will be stored in the array. Finally, the program uses the printf function to print the contents of the "name" array, which will output "Prog".Rate this question:

1 2 3 4
- D.
1
Correct Answer
D. 1Explanation
The program uses a do-while loop to print the value of the variable i. It starts with i=1 and increments it by 1 in each iteration. The condition for the loop to continue is TRUE, which is equivalent to the value 1. However, there is a break statement inside the loop that will be executed when i becomes greater than 5. Therefore, the loop will only iterate 5 times, printing the values 1, 2, 3, 4, and 5.Rate this question:

What will be the output of the following program ? #include<stdio.h> int main(){ typedef struct{char ch;}st; st s1 = {'c'}; st s2 = s1; if(s1 == s2) printf("Successful"); return 0; }
- A.
Successful
- B.
Compiler error
- C.
Compiler warning
- D.
None of these
Correct Answer
B. Compiler errorExplanation
The program will result in a compiler error. This is because the comparison operator (==) cannot be used to compare two struct variables. Struct variables cannot be directly compared using the equality operator.Rate this question:

What is the keyword used to turn off the compiler optimization of a variable?
- A.
Mutable
- B.
Volatile
- C.
Static
- D.
None of these
Correct Answer
B. VolatileExplanation
The keyword "volatile" is used to turn off the compiler optimization of a variable. When a variable is declared as volatile, it tells the compiler that the value of the variable can be changed unexpectedly by external factors, such as another thread or hardware. This prevents the compiler from optimizing the variable by caching its value, ensuring that the variable is always read from memory and not from a cached value. This is useful in scenarios where the variable's value can be modified outside of the program's control.Rate this question:

What will be the output of the following program? #include<stdio.h> int main() { fun(); } fun() { printf("you are in fun"); main(); return 0; }
- A.
It will print "you are in fun" endlessly
- B.
Infinite loop
- C.
It is an example of tree recursion
- D.
Stack overflow
Correct Answer
D. Stack overflowExplanation
The program will go into an infinite loop and print "you are in fun" endlessly. This is because the function fun() is calling the main() function recursively, creating an infinite loop. Eventually, the recursive calls will cause a stack overflow error, leading to the program crashing.Rate this question:

Which one of the following is the correct way of declaring main() function when it receives command line arguments?
- A.
Main(int argc, char argv)
- B.
Main(char argv[ ], int *argc)
- C.
Main(char* argv[ ],int argc)
- D.
Main(int argc,char* argv[ ])
Correct Answer
D. Main(int argc,char* argv[ ])Explanation
The correct way of declaring the main() function when it receives command line arguments is "main(int argc,char* argv[ ])". In this declaration, "argc" represents the number of command line arguments passed to the program, and "argv" is an array of strings containing the actual arguments.Rate this question:
