请教各位大侠,下面代码中的randnum=rand()%3+3;在这里有什么用,小女子知道rand()%3+3取得到的随机数是3到5,但是不是很清楚放在这段代码中有什么用。
int randnum,x,i;
web_url("localhost",
"URL=http://localhost/",
"TargetFrame=",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",

LAST);
randnum=rand()%3+3;
lr_output_message("%d",randnum);
for(i=0;i<randnum;i++)
{
lr_save_string(lr_eval_string("{categoryid}"),"temp");
web_url(lr_eval_string("{temp}"),
