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

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

Output:

hello.c
