std::strrchr: std::strrchr

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 <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
