Question

我是新来的。我的C ++大学课程结束后有点生锈。我正在尝试制作一个程序，其中特定的击键记录在cout中看到的文本。我遇到的问题是计时器功能阻止了 main 功能的继续。每次 Delay 达到28时，都会使用 timer 功能将 Tic 增大1。 timer 循环播放以及达到该时间时28，延迟重置为0。为什么我的 main 没有继续？是否正在等待定时器完成循环？如何使计时器和主机同时工作？这不是家庭作业。制作个人项目。

Answer 1

  while(TRUE)
    {
        if(Delay == 28)//Aprox to 1 tic
        {
            Delay = 0;//Reset delay to 0
            Tic ++;//Increase Tic by 1
        }
        else
        {
            Delay ++;//Increase Delay until it is at 28
        }
        Sleep(0.1);
    }

没有办法摆脱这种循环。您是否要在break块中放置if？也许while (Delay > 0)（最初设置为1）。

此外，如注释中所述，如果您说一个函数返回int，则需要确保该函数在每个路径上都有一个return语句。也许您只是想break而不是return Tic;？
