输入格式你是不是弄错了？

不行呀，我只会改成getline(cin,s);但是还不对

你可以看看这个（我的）AC代码：
```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
string s;
cin >> s;
int a = 0,b = 0,c = 0;
for (int i = 0;i < s.size();i += 5){//一个赋值语句长度为5（参见题目）
if (s[i] == 'a'){
if ('0' <= s[i + 3] && s[i + 3] <= '9'){//变量赋值数字
a = (int)(s[i + 3] - '0');
}
//变量赋值变量
if (s[i + 3] == 'b') a = b;
if (s[i + 3] == 'c') a = c;
}
//同样的
if (s[i] == 'b'){
if ('0' <= s[i + 3] && s[i + 3] <= '9'){
b = (int)(s[i + 3] - '0');
}
if (s[i + 3] == 'a') b = a;
if (s[i + 3] == 'c') b = c;
}
if (s[i] == 'c'){
if ('0' <= s[i + 3] && s[i + 3] <= '9'){
c = (int)(s[i + 3] - '0');
}
if (s[i + 3] == 'b') c = b;
if (s[i + 3] == 'a') c = a;
}
}
cout << a << " " << b << " " << c;
return 0;
}
```
和一些题目中的测试数据：
1.in: `a:=3;b:=b;c:=a;b:=8;a:=b;`
1.out: `8 8 3`
3.in: `b:=2;a:=5;c:=a;a:=b;b:=c;`
3.out: `2 5 5
`
