打表英雄到此一游

怕一些人抄我答案，所以设置了一点坑...... （往下看！）

include <bits/stdc++.h>

using namespace std; int ans; void ddd(){cout << "Divided by zero!" << endl;} void ddd2(){cout << "Invalid operator!" << endl;} void bbb(){cout << ans << endl;} main() {

int a,b;
char 
ans = (c=='+'?a+b:(c=='-'?a-b:(c=='*'?a*b:(c=='/'?(b==0?-1:a/b):-2;
ans==-1?ddd():(ans==-2?ddd2():bbb());
return 0;

}

include <bits/stdc++.h>

using namespace std; int ans; void ddd(){cout << "Divided by zero!" << endl;} void ddd2(){cout << "Invalid operator!" << endl;} void bbb(){cout << ans << endl;} signed main() {

int a,b;
char c;
cin >> a >> c >> b;
ans = (c=='+'?a+b:(c=='-'?a-b:(c=='*'?a*b:(c=='/'?(b==0?-1:a/b):-2))));
ans==-1?ddd():(ans==-2?ddd2():bbb());
return 0;

} （这是正确答案！）
