C++ 程序：判断数字关系并输出对应文字

#include <iostream>
using namespace std;

int main() {
    int N;
    cin >> N;
    
    for (int i = 0; i < N; i++) {
        int A, B, C;
        cin >> A >> B >> C;
        
        if (C == A * B) {
            cout << 'Lv Yan' << endl;
        } else if (C == A + B) {
            cout << 'Tu Dou' << endl;
        } else {
            cout << 'zhe du shi sha ya!' << endl;
        }
    }
    
    return 0;
}
