std::strrchr(3)

NAME
std::strrchr - std::strrchr

Synopsis
   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 <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
