Syntax

#include <string.h>
char *strchr(const char *string, int c);

strchr finds the first occurrence of a byte in a string. The byte c can be the null byte (\0); the ending null byte of string is included in the search.

The strchr function operates on null-terminated strings. The string arguments to the function should contain a null byte (\0) marking the end of the string.

strchr returns a pointer to the first occurrence of c in string. The function returns NULL if the specified byte is not found.

This example finds the first occurrence of the character p in "computer program".

#include <stdio.h>
#include <string.h>

#define  SIZE          40

int main(void)
{
   char buffer1[SIZE] = "computer program";
   char *ptr;
   int ch = 'p';

   ptr = strchr(buffer1, ch);
   printf("The first occurrence of %c in '%s' is '%s'\n", ch, buffer1, ptr);
   return 0;

   /****************************************************************************
      The output should be:

      The first occurrence of p in 'computer program' is 'puter program'
   ****************************************************************************/
