定时C程序循环 [英] Timed C Program Loop

问题描述

我需要根据用户输入(在C程序中)循环一定时间.

I need to loop for a certain amount of time based on user input ( in C Program ).

示例:用户说循环2分钟(= 120秒).

Example: User says loop for 2 Minutes ( = 120 seconds).

while(time <= 2 Minutes)
{
    do something
}

我将如何在C语言中执行此操作?谢谢您的帮助！

How would I go about doing this in C? Thanks for your help!!

推荐答案

如果需要在特定时间段内执行多次操作，则可以使用

If you need to perform some operation as many times as possible within the specific period of time you can use time():

time_t secs = 120; // 2 minutes (can be retrieved from user's input)

time_t startTime = time(NULL);
while (time(NULL) - startTime < secs)
{
    ...
}
