int rand();

看看这个程序吧，有点意思，当然这不是我写的：


#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define LEN 14
int main(void)
{
char *name[]={
"学C语言"
, "学VB"
, "学C++"
, "学JAVA"
, "学Delphi"
, "学汇编"
, "学ASP"
, "学Ajax"
, "学PHP"
, "学Javascript"
, "学XML"
, "学.NET"
, "学C#"
, "** 啥也不学了"
};

srand((unsigned)time(NULL));
printf("我要： %s !\n", name[rand()%LEN]);
}
return 0;
}

srand(time(null)); /*以时间取随机*/
for(i=0;i<N;i++)
a[i]=rand();

再冒泡把
