无论用户输入什么，C++ cin 都会为整数返回 0

Question

无论 cin 是什么，它都会继续输出 0 的分数。这是为什么？我尝试返回“return 0;”但还是不行:/

#include "stdafx.h"
#include <iostream>

using namespace std;

// Variables
int enemiesKilled;
const int KILLS = 150;
int score = enemiesKilled * KILLS; 

int main()
{
    cout << "How many enemies did you kill?" << endl;
    cin >> enemiesKilled;
    cout << "Your score: " << score << endl;
    return 0;
}

Answer 1

您需要在用户输入后执行乘法:

int main()
{
    cout << "How many enemies did you kill?" << endl;
    cin >> enemiesKilled;
    int score = enemiesKilled * KILLS;
    cout << "Your score: " << score << endl;
    return 0;
}
