    Which of these comes on secondary constants.

    • Character constant

    • Pointer

    Correct Answer
    A. Pointer
    Explanation
    Secondary constants refer to constants that are derived from primary constants. In this case, a pointer is considered a secondary constant because it is derived from a primary constant, which is the address of a variable. Pointers are used to store memory addresses, allowing for indirect access to data. Therefore, a pointer is the correct answer as it falls under the category of secondary constants.

    There are __________ keywords in c language?

    Correct Answer
    32
    thirty two
    Explanation
    The correct answer is 32. In the C language, there are 32 keywords. These keywords are reserved and have specific meanings in the language. They cannot be used as variable names or identifiers in the program. Some examples of C keywords include "if," "for," "while," and "int."

  • 7. 

    One function which is   __________ important to declare in C programming.?

    Correct Answer
    main
    Explanation
    The "main" function is the most important function to declare in C programming because it is the entry point of a C program. It is the starting point of execution and contains the code that will be executed when the program is run. Without the "main" function, the program will not be able to run and produce any output.

    Is c a middle-level language?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Yes, "c" is considered a middle-level language. Middle-level languages, like C, have features from both low-level languages (such as assembly language) and high-level languages (such as Python or Java). C provides low-level access to memory and hardware, allowing for efficient programming, while also offering higher-level features like functions and data structures. This makes C a versatile language that can be used for system-level programming, as well as application development.

    Rate this question:

  • 11. 

    Both the inverted comma's should point to the left eg: 'b' is a true statement.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given answer is true because the statement states that both the inverted commas should point to the left. Since the inverted commas in the example are indeed pointing to the left, the answer is true.

  • 12. 

    When you declare a variable of char type what's its range? example: char i = 'a'

    • 0 to 255

    • -128 to 127

    Correct Answer
    A. -128 to 127
    Explanation
    When you declare a variable of char type, its range is from -128 to 127. This is because char is a signed data type in C++, which means it can hold both positive and negative values. The range of -128 to 127 allows char to represent a total of 256 different values, including both positive and negative numbers.

    Why programmers find goto keyword seductive?

    • Unreliable

    • Unreadable

    • Hard to debug

    • All of those

    Correct Answer
    A. All of those
    Explanation
    Programmers find the goto keyword seductive because it allows them to have more control over the flow of their code. However, it is considered unreliable because it can lead to spaghetti code and make the program difficult to read and understand. Additionally, using goto can make debugging more challenging as it can create unexpected jumps in the code execution. Therefore, all of these reasons contribute to why programmers find the goto keyword seductive.

    Which thing do we write under two brace () in case-control structure?

    • Statement

    • Expression

    • Constant value

    • Any variable

    Correct Answer
    A. Expression
    Explanation
    In a case-control structure, we write an expression within the two braces (). An expression is a combination of variables, constants, and operators that produces a value. It can be a mathematical calculation, a comparison, or any other operation that evaluates to a value. Within the case-control structure, the expression is used to determine which block of code should be executed based on the condition specified.

    A break is usually associated with an __________?

    Correct Answer
    if
    Explanation
    A break is usually associated with an "if" statement in programming. The "if" statement is used to conditionally execute a block of code based on a certain condition. When the condition specified in the "if" statement is true, the code inside the block is executed, otherwise, it is skipped. Therefore, a break statement is commonly used within an "if" statement to terminate the execution of the block of code and exit the loop or switch statement that contains it.

    Break keyword _________out of a loop instantly?

    Correct Answer
    jump
    Explanation
    The "jump" keyword is used to break out of a loop instantly. It allows the program to skip the remaining iterations of the loop and continue executing the code after the loop. This is useful when a specific condition is met and the program needs to exit the loop immediately.

    Rate this question:

  • 18. 

    When continue is encountered  inside any loop, control automatically passes to the __________of the loop?

    Correct Answer
    beginning
    Explanation
    When continue is encountered inside any loop, control automatically passes to the beginning of the loop. This means that the remaining statements within the loop are skipped and the loop starts again from the beginning, evaluating the loop condition and executing the loop body again if the condition is true. This allows the loop to continue iterating without executing the remaining statements in the current iteration.

    What is the proper syntax for do-while?

    • Do { statement} while {condition};

    • Do { statement} while {condition}{statement}

    • Do { statement} while (condition) {statement}

    • Do { statement} while (condition) {statement};

    Correct Answer
    A. Do { statement} while (condition) {statement};
    Explanation
    The correct answer is "do { statement} while (condition) {statement};" because it follows the proper syntax for a do-while loop. In a do-while loop, the statements inside the curly braces are executed at least once, and then the condition inside the parentheses is checked. If the condition is true, the statements are executed again, and this process continues until the condition becomes false. The semicolon at the end of the loop is also necessary to indicate the end of the loop statement.

  • 20. 

    Int a = 1; printf ("%d%d",a,++a,a++); What is the output of the following program?

    • 122

    • 123

    • 331

    • 321

    Correct Answer
    A. 331
    Explanation
    The output of the program is 331. In the printf statement, the first occurrence of %d prints the value of a, which is 1. The second occurrence of %d is evaluated as ++a, which increments the value of a to 2 and returns the incremented value. So, the second occurrence of %d also prints 2. Finally, the third occurrence of %d is evaluated as a++, which returns the current value of a (2) and then increments it to 3. Therefore, the third occurrence of %d prints 3. Hence, the output is 331.
