Question

无论是cin还是继续输出0得分。这是为什么？我试着返回“return 0;”但仍然没有去：/

#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

您需要在用户输入输入后执行乘法运算：

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

Answer 2

您需要在用户输入号码后重新计算score 。

Answer 3

cin >> enemiesKilled;
score = enemiesKilled * KILLS; // <-- Put the calculation here!!
cout << "Your score: " << score << endl;

Answer 4

程序启动时，

int enemiesKilled;初始化为0.

int score = enemiesKilled * KILLS;同时计算。由于enemiesKilled为0，因此它也为0.

如其他答案中所述，您需要在运行时计算score。

无论用户输入什么，C ++ cin都返回0表示整数
