提示

	Java程序要求主类名为Main，且保存在缺省包中，即本题的答案如下：


	import java.util.Scanner;


public class Main {


       public static void main(String[] args) {

            Scanner input = new Scanner(System.in);

            int a=input.nextInt();

            int b=input.nextInt();

            System.out.println(a+b);

        }


}

C语言解答

#include <stdio.h>
int main()
{
  int a,b;
  scanf("%d %d",&a,&b);
  printf("%d",a+b);
  return 0;
}

C++解答

#include<iostream>
using namespace std;

int main()
{
	int a, b;
	cin >> a;
	cin >> b;
	cout << a + b;
	getchar();
	getchar();
	return 0;
}
