等待特定时间范围的输入 [英] Waits for input for certain time frame

问题描述

我只是C ++的初学者，并尝试完成一个简单的功能。



假设我有前3行：



int age;

cout<<请输入您的年龄<< endl;

cin>> age;





我希望这个函数等待30秒，如果有任何整数输入，则执行函数A，否则有没有用户输入并且时间到了，执行功能B.



我知道函数sleep可以很好地等待，但程序会等到有输入，30秒后不会停止。



请帮助，谢谢。

I am just a beginner of C++ and trying to get a simple function done.

Lets say i have these first 3 lines:

int age;
cout<<"please enter your age"<<endl;
cin>>age;


I want this function to wait for 30 seconds, if there is any input of integer, function A is executed, else there is no input by the user and the time is up, function B is executed.

I know the function sleep works well for waiting, but the program waits until there is input, not stopping after 30 seconds.

Please help, thank you.
