输入两个数,a,b
  
  
    输出
  
  
   输出a+b的值
  
  
    样例输入
  
  
2 3
  
    样例输出

    提示
  
  
   例如:
   
 C语言版:
   
 #include<stdio.h>
   
 int main()
   
 {
   
 int a,b;
   
 scanf("%d%d",&a,&b);
   
 printf("%d\n",a+b);
   
 } 
   
 C++版:
   
 #include<iostream>
   
 using namespace std;
   
 int main()
   
 {
   
 int a,b;
   
 cin>>a>>b;
   
 cout<<a+b<<endl;
   
 } 
   
 Java版:
   
 import java.io.*;
   
 import java.util.*;
   
 public class Main
   
 {
   
 public static void main(String args[]) throws Exception
   
 {
   
 Scanner cin=new Scanner(System.in);
   
 int a=cin.nextInt(),b=cin.nextInt();
   
 System.out.println(a+b);
   
 }
   
 }
   
 Java jdk 1.4 版
   
 import java.io.*;
   
 import java.util.*;
   
 public class Main
   
 {
   
 public static void main (String args[]) throws Exception
   
 {
   
 BufferedReader stdin = 
   
 new BufferedReader(
   
 new InputStreamReader(System.in));
   
 String line = stdin.readLine();
   
 StringTokenizer st = new StringTokenizer(line);
   
 int a = Integer.parseInt(st.nextToken());
   
 int b = Integer.parseInt(st.nextToken());
   
 System.out.println(a+b);
   
 }
   
 }
   
 请注意不要输出过多提示性语句(如:“please input two numbers”),不然会WrongAnswer的 
   
#include<stdio.h>
int main (){
int a,b;
scanf("%d%d",&a,&b);
printf("%d ",a+b);
return 0;
}
