strchr() returns a pointer value to locate first occurrence of "char" in the string "character". If no match is found a NULL pointer is returned by this manipulation function.

    char * strchr ( const char * str, int character );

   #include <stdio.h>
   #include <cstring.h>
   int main ()
    {
      char arr[] = "Hscripts is web resource site.";
      char * pnt;
      pnt=strchr(arr,'p');
      printf ("Character p was found first at 
             %dth place.\n",pnt-arr+1);
      return 0;
    }

    Character p was found first at 6th place.

In the above example strchr() manipulation function is used to return the pointer "pnt". Since strings are null terminated, array "pnt-arr+1" is used to locate the first occurence of "p".
