太难啦

#include<iostream> using namespace std; int main(){ long long a,b,c; cin>>a>>b>>c; cout<<a+b+c; return 0; }

要 long long

#include<iostream> using namespace std; int main(){ long long a,b,c; cin>>a>>b>>c; cout<<a+b+c; return 0; }

#include<iostream> using namespace std; int main(){ long long int a,b,c; cin>>a>>b>>c; cout<<a+b+c; return 0; }删除文本

#include<bits/stdc++.h> using namespace std; int main(){ long long a , b , c; cin >> a >> b >> c; cout << a + b + c; return 0; }

#include<iostream> using namespace std; int main(){ long long a,b,c; cin>>a>>b>>c; cout<<a+b+c; return 0; }
