思路：模拟。

AC代码：

 1 #include<bits/stdc++.h>
 2 using namespace std;
 3 int main()
 4 
 5     int x,y,z;
 6     while(cin >> x >> y >> z)
 7     
 8         if(x == y)
 9         
10             if(z == 0) cout << 0 << endl;
11             else cout << "?" << endl;
12         
13         else if(x > y)
14         
15             if(x - y > z) cout << "+" <<  endl;
16             else cout <<  "?" << endl;
17         
18         else
19         
20             if(y - x > z) cout << "-" << endl;
21             else cout <<  "?" << endl;
22         
23     
24     return 0;
