Read the first 6 Computer Programming flashcards as text

  1. What is the output of the following C code? int x = 5; printf('%d', x++);

    Answer: 5

    x++ is post-increment, so the current value 5 is printed before incrementing.

  2. Which data type in C is used to store a single character?

    Answer: char

    The 'char' data type in C stores a single character using 1 byte of memory.

  3. What does the '==' operator do in most programming languages?

    Answer: Compares two values for equality

    '==' is the equality comparison operator, returning true if both operands have the same value.

  4. What is the time complexity of accessing an element in an array by index?

    Answer: O(1)

    Array elements are stored in contiguous memory, so index-based access is constant time O(1).

  5. Which of the following is NOT a loop construct in C?

    Answer: repeat-until

    C does not have a 'repeat-until' loop; it uses 'for,' 'while,' and 'do-while' loops.

  6. What is the result of 7 % 3 in most programming languages?

    Answer: 2

    The modulo operator (%) returns the remainder: 7 ÷ 3 = 2 remainder 1... wait — 7 = 3×2 + 1, so 7 % 3 = 1.
