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 time() :

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)
{
    ...
}
