我正在尝试让 C 程序使用 clock_t 中的“秒”作为 for 循环计数器。这怎么可能?下面是我的编码,它不起作用,
#include<stdio.h>
#include <time.h>
int main()
{
clock_t begin, end;
double time_spent;
begin = clock();
time_spent = (double)begin / CLOCKS_PER_SEC;
for(time_spent=0.0; time_spent<62000.0; time_spent++)
{
printf("hello \n");
if(time_spent==5.0)
break;
}
end = clock();
time_spent = (double)(end - begin) / CLOCKS_PER_SEC;
printf(" %lf\n", time_spent);
}
