不太一样，但AC

#include <iostream>
using namespace std;
int main()
{
	int n=1,a, b;
	while(n==1)
	{
		cin>>a>>b;
		cout <<a+b<< endl;
	}
	return 0;
}

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

#include<stdio.h> #include using namespace std; int main() { int a,b; while(cin>>a>>b) cout<<a+b<<endl;

//while(scanf("%d%d"),&a,&b)!=EOF)
//	printf("%d\n",a+b);

}

#include

using namespace std;

int main() {

int n=1,a,b;

while(cin>>a>>b){

}

}

#include <stdio.h>

int main() {

while ((scanf("%d %d", &a, &b)) != EOF)

printf("%d\n", a + b);

return 0;
