我用sleep语句的时候报错【未定义对sleep的引用】,网上找到的信息有的人说【mingw舍弃了sleep函数】,有的人说【使用windows api函数 Sleep或者c++11 标准新增加的this_thread::sleep_for()】,有的人说【mingw下的sleep问题:SetErrorMode、Beep和Sleep三个函数舍弃了,可以使用win32 API对应的函数】。。。 可我真心...

Sleep就是把自己挂起,结束当前时间片 例如: #include<iostream> #include<windows.h> using namespace std; int main() { Sleep(3000);//暂停3秒 S要大写 return 0; } Usestd::this_thread::sleep_for: :::(111605// or whatever:::(); There...
#include <chrono> #include <thread> int main() { // 休眠 2 秒 std::this_thread::sleep_for(std::chrono::seconds(2)); return 0; } 请注意,sleep_for 是 std::this_thread 命名空间中的一个函数,它接受一 个 std::chrono::duration 作为参数。在这种情况下,我们使 用 std::chrono::seconds...
