Description

The strpbrk function locates in the null-terminated string s the first occurrence of any character in the string charset and returns a pointer to this character. If no characters from charset occur anywhere in s strpbrk returns NULL.

#include <stdio.h>
#include <string.h>
int main()
{
  char s[20] = "abcde1010101", t[3] = "01";
  printf("The position of the first binary digit of s is: %d.\n", strpbrk(s, t) - s);
  return 0;
}

The position of the first binary digit of s is: 5.
