好多a+b

#include <stdio.h> #include <iostream> using namespace std; int main() { int n , sum ; cin >> n; for (int i = 1 ; i <= n ; i++) { if (i%7 == 0) continue; int k = i; while (k) { if (k%10 ==7) break; k /= 10; } if (!k) sum +=i*i; } cout << sum << endl; }

#include<iostream>

using namespace std;

int main() {

int n=1,a,b;

while(cin>>a>>b){

cout<<a+b<<endl<<" "<<endl;

}

}
