Can you explain in detail what the following code does?

void solve() {
 char c;
 std::cin >> c;
 
 if (std::string("codeforces").find(c) != std::string::npos) {
 std::cout << "YES\n";
 } else {
 std::cout << "NO\n";
 }
}

Μπορείς να εξηγήσεις αναλυτικά τι κάνει ο παρακάτω κώδικας;

void solve() {
char c;

std::cin >> c;

if (std::string("codeforces").find(c) != std::string::npos) {
std::cout << "YES\n";
} else {
std::cout << "NO\n";
}
}
