Defined in header <cstring>
const char* strrchr( const char* str, int ch );
char* strrchr(       char* str, int ch );

Finds the last occurrence of ch (after conversion to char) in the byte string pointed to by str. The terminating null character is considered to be a part of the string and can be found if searching for '\0'.

Parameters

str	-	pointer to the null-terminated byte string to be analyzed
ch	-	character to search for

Return value

Pointer to the found character in str, or null pointer if no such character is found.

Example

Run this code

#include <iostream>
#include <cstring>
 
int main()
{
    char input[] = "/home/user/hello.c";
    char* output = std::strrchr(input, '/');
    if(output)
        std::cout << output+1 << '\n';
}

Output:

hello.c
