Question

我目前正在尝试学习C ++，我编写了以下程序。它确实应该成功，但它会自动退出。我已经尝试在最后放置一个cin，当它没有工作时，我放了一个getChar()并且它不会等待任何输入。要明确的是，我没有接受过关于C ++的正规教育，这个问题让我很难过。我试过谷歌搜索它，但所有出现的是它告诉我使用我已经尝试过的任何一件事。我已经注释了cin断点，以显示我放置它们的位置。

正如我之前所说，该程序的实际代码如下。下面是调试日志。

为了它的价值，我使用Visual Studio来实现这个目标。

编辑：这不是一个重复的问题，因为我希望能够使用实际的可执行文件，双击它并让它等待我按键直到它退出。有了这个程序，即使我转到实际的可执行文件，它仍会自动退出。

代码

该计划的代码：

#include <iostream>
#include <string>
using namespace std;

// Declare variables for intro
string intro = "Please enter your score.\n";
string prompt = ">>> ";
string nl = "\n";

// Declare grade calculation variables
int initial_grade = 0;
bool temp;

// Declare variables for perfection test
string perfect_score = "You scored perfectly, congratulations!\n";

void perfection_test() {
    switch (initial_grade) {
    case 100:
        cout << perfect_score;
        //cin;
    }
    //cin;

}

int main() {
    cout << intro << prompt;
    cin >> initial_grade;
    cout << nl;

    //cin;
    perfection_test();
    //cin;
}
