Question

include了time.h头文件但还是有错误error C2660: 'time' : function does not take 0 parameters

#include<time.h>
....
t=time()%1000;
error C2660: 'time' : function does not take 0 parameters

Answer 1

function does not take 0 parameters // time函数不接受0个参数
要传递一个参数 : 函数原型：time_t time(time_t * timer)
可以这样 time(NULL)

Answer 2

srand((usigned)time(null));
