Another one guys....

35.  All of the following choices represent syntactically correct function definitions.

        Which one of the following represents a semantically legal function definition in Standard C?

(a)

 int count_digits (const char * buf)

{

 assert(buf != NULL);

  int cnt = 0, i;

  for (i = 0; buf[i] != '\0'; i++)

    if (isdigit(buf[i]))

      cnt++;

 return cnt;

}

 

This should be the answer

(b)

 int count_digits (const char * buf) {

 int cnt = 0;

 assert(buf != NULL);

  for (int i = 0; buf[i] != '\0'; i++)

    if (isdigit(buf[i]))

      cnt++;

  return cnt;

}

92.compilation error(need constant value in array subscript).

even quest 30 is showing compilatio error only.
