大家帮忙看看原因何在

[miningNET]

#include <iostream>
using namespace std;
void main()
{
int i;
cin>>i;
switch(i)
{
case 1:
int j=1;
cout<<j<<endl;
break;
case 2:
int k=2;
cout<<k<<endl;
break;
case 3:
cout<<"error!"<<endl;
break;
}
}
编译出错：

我也遇到过这样的情况，好象在CASE语句里面不能定义变量，应该在switch语句之外定义。

[wangkeyunanjing]

case 语句中不能定义变量，除非用{}括起来

int j=1;
int k=2; 都放在switch(i)前面。
