我这程序怎么还是没法运行

[sunsold]

把这个程序改了 可是怎么还是没法运行
而且让电脑代替人模拟10000次并且记录change和不change的获胜次数我也不会!!!!!!!急啊

#include <iostream>
#include <cstdlib>
#include <time.h>

using namespace std;

int select,door;

void main()
{

door=rand()%3+1;
cout <<"you can choose one door of the three" <<endl;
cin>>select;
if(select==door)
void same();
else
void different();

}

void same()
{
int select1;

switch(select1)
case 1:
cout<<"The door2 has a consolation prize.Do you want to change your select"<<endl;
case 2:
cout<<"The door1 has a consolation prize.Do you want to change your select"<<endl;
case 3:
cout<<"The door2 has a consolation prize.Do you want to change your select"<<endl;

cout<<"please select again: door1 door2 door3"<<endl;
cin>>select1;

if(select1==door)
cout<<"You win the game"<<endl;
else
cout<<"You lose"<<endl;
}
void different()
{
int select2;

switch(select2)
case select==1,door==2:
cout<<"The door3 has a consolation prize.Do you want to change your select"<<endl;
case select==2,door==1:
cout<<"The door3 has a consolation prize.Do you want to change your select"<<endl;
case select==3,door==1:
cout<<"The door2 has a consolation prize.Do you want to change your select"<<endl;
case select==1,door==3:
cout<<"The door2 has a consolation prize.Do you want to change your select"<<endl;
case select==2,door==3:
cout<<"The door1 has a consolation prize.Do you want to change your select"<<endl;
case select==3,door==2:
cout<<"The door1 has a consolation prize.Do you want to change your select"<<endl;


cout<<"please select again: door1 door2 door3"<<endl;
cin>>select2;

if(select2==door)
cout<<"You win the game"<<endl;
else
cout<<"You lose"<<endl;
}

[lingyin55]

void same()
{
int select1; //这里都没有初始化，怎么用switch判断啊？？

switch(select1)

[lingyin55]

void different()
{
int select2; //这个也一样

switch(select2)


你应该定义函数的入参，比如

void same( int i )
{
int select1 = i;
//下面是你的程序
}

void different( int i )
{
//同上
}


//主函数调用
main()
{
//....
same(select);
//....
different(select);
}
//另外你定义的变量door也是没有初始化，而且看似没有什么作用。程序很乱，自己再整理吧
