如何阻止 C++ 控制台应用程序立即退出？
So im learning c++ and i was given this example and i wanted to run it. But i cannot get it to stay up, unless i change it. How do i get Microsoft visual 2010 to keep up the screen when it gets to the end of the program after I release it?
所以我正在学习 C++，我得到了这个例子，我想运行它。但我不能让它熬夜，除非我改变它。我如何让 Microsoft Visual 2010 在我发布程序结束时保持屏幕显示？
#include<iostream>
using namespace std;
int area(int length, int width); /* function declaration */
/* MAIN PROGRAM: */
int main()
{
int this_length, this_width;
cout << "Enter the length: "; /* <--- line 9 */
cin >> this_length;
cout << "Enter the width: ";
cin >> this_width;
cout << "\n"; /* <--- line 13 */
cout << "The area of a " << this_length << "x" << this_width;
cout << " rectangle is " << area(this_length, this_width);
return 0;
}
/* END OF MAIN PROGRAM */
/* FUNCTION TO CALCULATE AREA: */
int area(int length, int width) /* start of function definition */
{
int number;
number = length * width;
return number;
} /* end of function definition */
/* END OF FUNCTION */

In Visual C++ you can either:
在 Visual C++ 中，您可以：
- Put a breakpoint at the closing brace of
mainand run attached to the debugger (Debug -> Start Debugging). When the breakpoint is hit you will be able to view the console window. - Run detached from the debugger (Debug -> Start Without Debugging). When the application terminates, the console window will stay open with a "Press any key to continue..." prompt.
- 在右大括号处放置一个断点
main并运行附加到调试器（调试 -> 开始调试）。当断点被击中时，您将能够查看控制台窗口。 - 从调试器分离运行（调试 -> 不调试启动）。当应用程序终止时，控制台窗口将保持打开状态，并显示“按任意键继续...”提示。

I usually use cin.getchar() to wait for a character.
我通常使用 cin.getchar() 来等待一个字符。

You already have the answer in your code.. add another cin at the end of your program ;P user would have to press enter for program to continue and exit
您的代码中已经有了答案.. 在程序末尾添加另一个 cin ；P 用户必须按 Enter 才能让程序继续并退出

Try adding system("PAUSE");to the end of mainbefore the returnstatement.
尝试添加system("PAUSE");到语句main之前的末尾return。
This executes the PAUSE system command which waits for a key to be pressed.
这将执行等待按键被按下的 PAUSE 系统命令。

The easiest way is to wait for the user to press a key before returning from main.
最简单的方法是在从 main 返回之前等待用户按下某个键。
