Syntax
#include <string.h> char *strrchr(const char *string, int c);Description
strrchr finds the last occurrence of c (converted to a byte) in string. The ending null byte is considered part of the string.
strrchr returns a pointer to the last occurrence of c in string. If the given byte is not found, a NULL pointer is returned.
This example compares the use of strchr and strrchr. It searches the string for the first and last occurrence of p in the string.
#include <stdio.h>
#include <string.h>
#define SIZE 40
int main(void)
{
char buf[SIZE] = "computer program";
char *ptr;
int ch = 'p';
/* This illustrates strchr */
ptr = strchr(buf, ch);
printf("The first occurrence of %c in '%s' is '%s'\n", ch, buf, ptr);
/* This illustrates strrchr */
ptr = strrchr(buf, ch);
printf("The last occurrence of %c in '%s' is '%s'\n", ch, buf, ptr);
return 0;

The output should be:
The first occurrence of p in 'computer program' is 'puter program'
The last occurrence of p in 'computer program' is 'program'
