    Macros are defined using ___________________ statement.

    • A.

      #define

    • B.

      #include

    Correct Answer
    A. #define
    Explanation
    Macros are defined using the "#define" statement. This statement is used in programming languages like C and C++ to define macros, which are essentially preprocessor directives that allow for the definition of constants or functions. The "#define" statement is followed by the name of the macro and its corresponding value or code. This allows for the easy substitution of the macro with its defined value throughout the code, providing a convenient way to simplify and reuse code.

    To find factorial of A by using while loop,  A will be ________________.

    • A.

      A

    • B.

      A>0

    Correct Answer
    B. A>0
    Explanation
    In order to find the factorial of A using a while loop, the condition in the while loop should be A>0. This means that the loop will continue executing as long as A is greater than 0. This is necessary because the factorial of a number is calculated by multiplying all the numbers from 1 to that number, and the loop needs to continue until it reaches 1.

    ___________________ keyword is used to exit loops at arbitrary spots.

    • A.

      Break

    • B.

      CLOSE

    Correct Answer
    A. Break
    Explanation
    The keyword "break" is used to exit loops at arbitrary spots. It is commonly used in programming languages like C, C++, and Java. When the "break" statement is encountered within a loop, the loop is immediately terminated and the program execution continues to the next statement after the loop. This allows for more control and flexibility in loop execution, as it allows programmers to exit the loop based on certain conditions or events.

    Rate this question:

    Rate this question:

  • 20. 

    A for loop is used to execute a section of code a specific number of times.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A for loop is a control structure in programming that allows a section of code to be executed repeatedly for a specific number of times. It consists of an initialization statement, a condition statement, an increment statement, and the code block to be executed. The loop continues until the condition statement evaluates to false. Therefore, the given statement is true, as a for loop is indeed used to execute a section of code a specific number of times.

    Rate this question:

  • 21. 

    A do while loop is very similar to a while loop.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A do while loop is indeed very similar to a while loop. Both loops are used for repetitive execution of a block of code based on a condition. The main difference is that in a do while loop, the block of code is executed at least once before checking the condition. After the first execution, the condition is checked, and if it is true, the loop continues. If the condition is false, the loop is terminated. This behavior makes the do while loop suitable for situations where the block of code needs to be executed at least once, regardless of the condition.

    Rate this question:

  • 22. 

    The break key word allows you to jump out of any loop at any time.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The break keyword is used in programming to exit or terminate a loop prematurely. When the break keyword is encountered within a loop, it immediately terminates the loop and program execution continues with the next statement after the loop. Therefore, it allows you to jump out of any loop at any time. So, the given statement is true.

    Rate this question:

  • 23. 

    The continue keyword is used in loops to skip right to the test condition.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The continue keyword is used in loops to skip the current iteration and move directly to the next iteration, without executing any further code within the loop for that iteration. This allows the loop to skip certain iterations based on a specific condition, and continue with the next iteration. Therefore, the statement "The continue keyword is used in loops to skip right to the test condition" is true.

    Rate this question:

  • 24. 

     The Return Statement is optional.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The return statement is optional in programming languages. This means that it is not always necessary to include a return statement in a function or method. If a return statement is not included, the function will still execute and perform any other actions or calculations specified within it, but it will not return a value. Including a return statement allows the function to return a specific value or result back to the caller. However, if a return statement is not needed or desired, it can be omitted.

    Rate this question:

  • 25. 

    In C all function except main() can be called recursively.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    In C, all functions can be called recursively, not just main(). Recursion is a programming technique where a function calls itself. This allows for solving complex problems by breaking them down into smaller, more manageable subproblems. Therefore, the correct answer is False.

    Rate this question:

  • 26. 

     In function two return statement should never occur.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because in a function, it is possible to have multiple return statements. The return statement is used to end the execution of a function and return a value. Depending on the logic and requirements of the function, there may be multiple points where a return statement is needed. So, it is not true that return statements should never occur in a function.

    Rate this question:

  • 27. 

     C program is developed with the help of C++ language.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is false because C and C++ are two separate programming languages. While C++ is an extension of the C language and includes all of its features, C programs cannot be developed with the help of C++ language. C and C++ have different syntax and features, and although C++ can incorporate C code, they are not interchangeable.

    If Else statement is used when both the statements are False.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement "If Else statement is used when both the statements are False" is incorrect. The If Else statement is used when there is a condition that can be either true or false. If the condition is true, the code inside the If block is executed, otherwise, the code inside the Else block is executed. Therefore, the correct answer is False.

    The C complier runs a program called the C Processor.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The C compiler is responsible for translating the C code into machine-readable instructions. It takes the source code as input and processes it to generate an executable program. The compiler performs various tasks such as lexical analysis, syntax analysis, semantic analysis, and code generation. The C Processor mentioned in the question is likely referring to the compiler itself, as it is the program that processes the C code. Therefore, the statement "The C compiler runs a program called the C Processor" is true.

    B. False
    Explanation
    A header file is a file that contains declarations and definitions of functions, variables, and other objects that can be used in a program. It typically includes function prototypes, type definitions, and macro definitions, but does not contain actual implementations or executable code. Therefore, a header file does not contain definitions and macros, but rather declarations and other necessary information for using them. Hence, the given statement is false.

    Rate this question:

  • 40. 

    A link is a Complier.

    • A.

      True

    • B.

      False

    Correct Answer
