strrchr() manipulation function is used to locate the last occurrence of a character in the string pointed by "str". If no match is located, a NULL pointer is returned.

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

   #include <stdio.h>
   #include <cstring.h>
   int main ()
     {
       char str[] = "Funmin.com online gaming webiste";
       char * pt;
       pt=strrchr(str,'i');
       printf ("Last occurence of 'i' is in 
                the %dst position.\n",pt-str+1);
       return 0;
     }

   Last occurence of 'i' is in the 29th position.

In the above example, strrchr() manipulation function is used to find the last occurence of "i" in the string "str".
