Defined in string.h.

Find last occurrence of character in string.
Returns the last occurrence of c in string.
The null-terminating character is included as part of the string and can also be searched.

Parameters.

• string Null-terminated string scanned in the search.
• c Character to be found.

Return Value.

• If character is found, a pointer to the last occurrence of c in string is returned.
• If not, NULL is returned.

Portability.

• Defined in ANSI-C.
• ANSI-C++ standard specifies two different declarations for this function instead of the one included in ANSI-C:

 const char * strrchr ( const char * string, int c );
       char * strrchr (       char * string, int c );

Both have the same behavior as the original declaration.

Example.

/* strrchr example */

include 
include 


int main ()
{
  char str[] = "This is a sample string";
  char * pch;
  pch=strrchr(str,'s');
  printf ("Last occurence of 's' found at %d \n",pch-str+1);
  return 0;
}

Output: Last occurrence of 's' found at 18
