strrchr

function
<cstring>
const char * strrchr ( const char * str, int character );
      char * strrchr (       char * str, int character );

Locate last occurrence of character in string

Returns a pointer to the last occurrence of character in the C string str.

The terminating null-character is considered part of the C string. Therefore, it can also be located to retrieve a pointer to the end of a string.

Parameters

str
C string.
character
Character to be located. It is passed as its int promotion, but it is internally converted back to char.

Return Value

A pointer to the last occurrence of character in str.
If the value is not found, the function returns a null pointer.

Portability

In C, this function is declared as:

char * strrchr ( const char *, int );
instead of the two overloaded versions provided in C++.

/* strrchr example */
#include <stdio.h>
#include <string.h>
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
