[問題] 想請問有關取得運算時間的函式
遇到的問題： 不知道哪裡有問題，運算的時間都一樣，不管fo迴圈跑多少次r
開發平台： (Dev-C++, Windows)
有問題的code：
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(void)
{
int begin,end,sum=0;
register int i,j;
printf("測試結果:\n");
begin=clock();
for(i=0;i<10000;i++)
for(j=0;j<10000;j++)
sum=sum+1;
end=clock();
printf("執行函式花了%g秒\n",(end-begin)/CLK_TCK);
system("pause");
return 0;
}
可以麻煩各位幫我看一下，哪裡有錯嗎？ 謝謝你們
