Predict the output?




#include <stdio.h>
int fun(char *str1)
{
  char *str2 = str1;
  while(*++str1);
  return (str1-str2);
}
  
int main()
{
  char *str = "GeeksQuiz";
  printf("%d", fun(str));
  return 0;
}


(A) 10
(B) 9
(C) 8
(D) Random Number


Answer: (B)

Explanation: The function fun() basically counts number of characters in input string. Inside fun(), pointer str2 is initialized as str1. The statement while(*++str1); increments str1 till ‘\0’ is reached. str1 is incremented by 9. Finally the difference between str2 and str1 is returned which is 9.
