timer.c

公司vc培训的时候,给大家几个例子,比较实用,拿来分享

#include<time.h>


main()
{
	clock_t time,deltime;
	long junk,i;
	float secs;
LOOP:
	printf("input loop count:  ");
	scanf("%ld",&junk);
	time = clock();
	for(i=0;i<junk;i++)
	deltime = clock() - time;
	secs = (float) deltime/CLOCKS_PER_SEC;
	printf("for %ld loops, #tics = %ld, time = %f\n",junk,deltime,secs);
	goto LOOP;
	return 0;
}
