产生随机数

#include<iostream>
#include<vector>
#include<ctime>
using namespace std;
void main()
{
    int N=8;
    srand(time(0));//以时间为种子
    int x=rand()%N;//产生0～N-1之间的随机数
    switch(x)
    {
        case 0:cout<<"sunyu"<<endl;break;
        case 1:cout<<"liyuanwen"<<endl;break;
        case 2:cout<<"yudenggao"<<endl;break;
        case 3:cout<<"wubo"<<endl;break;
        case 4:cout<<"yuguangshi"<<endl;break;
        case 5:cout<<"mashimin"<<endl;break;
        case 6:cout<<"zuogang"<<endl;break;
        case 7:cout<<"wangyu"<<endl;break;
