C语言实现多线程进度条显示最近做项目时发现一个有趣的东西，进度条，就想来怎么实现，查看别人写的都是在printf时加了一个’\r’,但是也只是实现了单线程的一个进度条显示，一下是多线程的进度条展示但是还是有问题的，如果有后续的打印就会出现打印错乱的问题，若有高手路经此地望指点一二 /***********************************************************************... 阅读详情

各位高手
如何实现每个线程打印各自的进度，
类似下面的输出
也就是说
在控制台下
每个线程输出一行
这行用来更新自己的进度

thanks

c# 多线程和异步委托实现进度条前言在我们应用程序开发过程中，经常会遇到一些问题，需要使用多线程技术来加以解决。本文就是通过几个示例程序给大家讲解一下多线程相关的一些主要问题。执行长任务操作　　许多种类的应用程序都需要长时间操作，比如：执行一个打印任务，请求一个 Web Service 调用等。用户在这种情况下一般会去转移做其他事情来等待任务的完成，同时还希望随时可以监控任务的执行进度。?/P>　　下面的代码片断阅读详情

main的最后加一句getchar();再试试。

使用控制台函数来实现位置和颜色之类的。诸如 SetConsoleCursorPosition
