  • 2. 

    C language has been developed by ?

    • Ken Thompson

    • Dennis Ritchie

    • Peter Norton

    • Martin Richards

    Correct Answer
    A. Dennis Ritchie
    Explanation
    Dennis Ritchie is the correct answer because he is widely recognized as the creator of the C programming language. Along with Ken Thompson, Ritchie developed C at Bell Labs in the early 1970s. C became popular due to its simplicity, efficiency, and ability to work closely with hardware, making it a foundational language for operating systems and low-level programming. Ritchie's contributions to C and other programming languages have had a significant impact on the field of computer science.

    C can be used on ?

    • Only MS-DOS

    • Only Linux

    • Only window

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    C can be used on all of the above operating systems, including MS-DOS, Linux, and Windows. C is a widely used programming language that is platform-independent, meaning it can be compiled and executed on different operating systems. Therefore, it is not limited to any specific operating system and can be used on all of the mentioned platforms.

    The maximun value that an integer constant can have is ?

    • -32767

    • 32767

    • 1.7014e+38

    • -1.7014e+38

    Correct Answer
    A. 32767
    Explanation
    The given answer, 32767, is the maximum value that an integer constant can have. This is because the range of a signed integer in most programming languages is typically from -32768 to 32767. Therefore, 32767 is the highest positive value that can be represented by an integer constant.

  • 5. 

    A character variable can at a time score ?

    • 1 character

    • 8 characters

    • 254 characters

    • None of the above

    Correct Answer
    A. 1 character
    Explanation
    A character variable can only store one character at a time. This means that it can hold a single character value such as a letter, number, or symbol. It cannot store multiple characters or a string of characters. Therefore, the correct answer is 1 character.

    Rate this question:

  • 6. 

    Which of the following is not a character constant ?

    • 'Thank You'

    • 'quest videos- IT Learning at its best'

    • '23.56e-03'

    • All of the above

    Correct Answer
    A. All of the above
  • 7. 

    The real constant in C can be expressed which of the following forms ?

    • Fractional form only

    • Exponetial form only

    • ASCII form only

    • Both Fractional and Exponetial

    Correct Answer
    A. Both Fractional and Exponetial
    Explanation
    The real constant in C can be expressed in both fractional and exponential forms. The fractional form represents a real number as a fraction, while the exponential form represents a real number as a base raised to an exponent. Both forms allow for the representation of real constants in C.

  • 8. 

    The statement char ch='z' would store in ch

    • The character Z

    • ASCII value of Z

    • Z along with the single inverted commas

    • Both (1) and (2)

    Correct Answer
    A. ASCII value of Z
    Explanation
    The statement char ch='z' would store the ASCII value of the character 'z' in the variable ch. In ASCII, the character 'z' has a decimal value of 122. Therefore, the correct answer is the ASCII value of Z.

    Rate this question:

  • 9. 

    Which of the following statements is wrong ?

    • INT=123;

    • Val='A' * 'B';

    • Is=20 * 'T'

    • Count+5=res;

    Correct Answer
    A. Count+5=res;
    Explanation
    The statement "count+5=res;" is wrong because it tries to assign a value to a variable "res" using an equation that includes the variable "count" and the number 5. However, the variable "count" has not been declared or assigned a value before this statement, so it is not possible to perform this assignment.

    Rate this question:

  • 10. 

    A C variable cannot start with ?

    • An alphabet

    • A number

    • A special symbol other than underscore

    • Both (2) and (3)

    Correct Answer
    A. Both (2) and (3)
    Explanation
    A C variable cannot start with a number or a special symbol other than an underscore. According to the C programming language rules, a variable name must start with an alphabet or an underscore, followed by any combination of alphabets, numbers, or underscores. Therefore, both options (2) and (3) are correct, as a C variable cannot start with a number or a special symbol other than an underscore.
