strchr

INTERFACE

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

DESCRIPTION

The strchr function locates the first occurrence of c (converted to a char) in the string pointed to by s. The terminating null character is considered part of the string; therefore if c is '\\0', the functions locate the terminating '\\0'.

The strrchr function is identical to strchr except it locates the last occurrence of c.

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

int main()
{
  // define some string
  char s[10] = "abcdefgh";

  // look for the character 'e' in the string s
  char *pos = strchr(s, 'e');

  // display search result
  if (pos)
    printf("Character 'e' found at position %d.\n", pos - s);
  else
    printf("Character 'e' not found.\n");

  return 0;
}

Character 'e' found at position 4.

RETURN VALUES

The functions strchr and strrchr return a pointer to the located character, or NULL if the character does not appear in the string.
