Which declaration creates a character array capable of storing the string "CAT" including its null character?

Options

  • A. char s[3] = "CAT";
  • B. char s[4] = "CAT";
  • C. char s[2] = "CAT";
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. char s[4] = "CAT";

Detailed Explanation

Answer: (B) char s[4] = "CAT";

A C-style string is terminated by a special null character, written as ''.

The string "CAT" contains three visible characters:

C, A, T

One additional position is required for the null character.

Therefore, the required size is:

3 + 1 = 4

Hence, char s[4] = "CAT"; is correct.
