Question

我使用了visual studio 2012，这是我第一次使用它。我开始了

NEW → Project-Empty → Project-source 然后 files-add →新项目-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;
}

我想制定一个计划，将美分分为dollars，quarters，nickels，dimes和pennies，.exe窗口成功形成，但在我输入数量后，我想转换窗口消失了。断点或系统（“暂停”）似乎不起作用。这是消息：

'Project2.exe' (Win32): Loaded 'C:\Users\dell\Documents\Visual Studio 2012\Projects\Project2\Debug\Project2.exe'. Symbols loaded. 'Project2.exe' (Win32): Loaded 'C:\Windows\SysWOW64\ntdll.dll'.

The program '[7476] Project2.exe' has exited with code -1073741510 (0xc000013a).

如何保留.exe窗口并查看结果？

Answer 1

程序中的返回码0xc000013a表示按下了CTRL-C，导致程序退出。你按CTRL-C了吗？

如果您对分数进行硬编码（例如说1999年），而不是提示用户输入数字，会发生什么？那么它是否正常工作？

如果添加“cin＆gt;＆gt;美分”，会发生什么？在 cout语句后显示计算值？

Answer 2

如果您要编写控制台程序，则应该从控制台运行它们。如果要编写要从GUI运行的程序，请编写GUI程序。

system("pause")无效的原因是您永远不会cout.flush();或cout << endl;。在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程序。
