#include <iostream>
#include <ctime>
/* delay time */
int main( )
{
using namespace std;
float secs;
cout<<"enter delay time:";
cin>>secs;
clock_t delay=secs*CLOCKS_PER_SEC;
cout<<"starting\a\n";
clock_t start=clock(); //clock() 經過多少系統時間
while(clock()-start<delay);
cout<<"done \a\n";
return 0;
}
顯示結果:
enter delay time: 3
starting
done
函式酷的定義: #define CLOCK_PER_SEC 1000
