c++ - .exe窗口退出后

Question

我使用了 Visual Studio 2012，这是我第一次使用它。我开始了

NEW→<kbd>Project-Empty→<kbd>Project-sourcethen files-add→<kbd>new items-Cpp文件并输入以下代码：

#include <iostream>
using namespace std;
int main()
{
    int cents;
    int dollars, quarters, dimes, nickels, pennies;

    cout << "Enter total cents: ";
    cin >> cents;

    dollars = cents / 100;
    cents = cents - dollars*100;
    quarters = cents / 25;
    cents = cents - quarters*25;
    dimes = cents / 10;
    cents = cents - dimes*10;
    nickels = cents / 5;
    cents = cents - nickels*5;
    pennies = cents;  

    cout << "This corresponds to "
         << dollars << " dollars, "
         << quarters << " quarters, "
         << dimes << " dimes, "
         << nickels << " nickels, and "
         << pennies << " pennies.\n\n";
    return 0;
}

我想编写一个程序将美分分解为dollars、quarters、和nickels，窗口已成功形成，但在我输入美分数后，我想转换的窗口消失了。断点或系统（“暂停”）似乎不起作用。这是消息：dimespennies.exe

如何保留.exe窗口并查看结果？

Answer 1

程序的返回代码0xc000013a表明按下了 CTRL-C，导致程序退出。您是否按了CTRL-C？

如果您硬编码美分的数量（例如 1999），而不是提示用户输入数字，会发生什么情况？那么它工作正常吗？

如果添加“cin >> cents;”会发生什么？在显示计算值的 cout 语句之后？

Answer 2

如果您要编写控制台程序，您应该从控制台运行它们。如果您想编写一个从 GUI 运行的程序，请编写一个 GUI 程序。

system("pause")没有工作的原因是你从不做cout.flush();或cout << endl;。在您实际产生输出之前暂停将无济于事。

Answer 3

使用ctrl+ F5在没有调试工具的情况下运行您的程序。
