How to check whether a string ends with another string in C++

Answer 1

#include <iostream>

using namespace std;
  
bool string_ends_with(const string s, const string match) {
    // int compare(size_t pos, size_t len, const string& str) const;
	if (s.size() >= match.size() && s.compare(s.size() - match.size(), match.size(), match) == 0)
		return true;
	else
		return false;
}
  
int main() {
    string s = "cpp java php python"; 
      
    if (string_ends_with(s, "python"))
        cout << "yes";
    else
        cout << "no";
}
 
 
  
/*
run:
  
yes
  
*/

#include <iostream>

using namespace std;
  
bool string_ends_with(const string &s, const string &match) {
    if (match.size() > s.size()) return false;

    return equal(match.rbegin(), match.rend(), s.rbegin());
}
  
int main() {
    string s = "cpp java php python"; 
      
    if (string_ends_with(s, "python"))
        cout << "yes";
    else
        cout << "no";
}
 
 
  
/*
