C에서 문자열이 다른 문자열로 끝나는지 확인하는 방법은 무엇입니까?

<code class="cpp">#include <iostream>
#include <string>

bool hasEnding(const std::string &fullString, const std::string &ending) {
    if (fullString.length() >= ending.length()) {
        return (0 == fullString.compare(fullString.length() - ending.length(), ending.length(), ending));
    } else {
        return false;
    }
}

int main() {
    std::string test1 = "binary";
    std::string test2 = "unary";
    std::string test3 = "tertiary";
    std::string test4 = "ry";
    std::string ending = "nary";

    std::cout << hasEnding(test1, ending) << std::endl;
    std::cout << hasEnding(test2, ending) << std::endl;
    std::cout << hasEnding(test3, ending) << std::endl;
    std::cout << hasEnding(test4, ending) << std::endl;

    return 0;
}</code>
