A+B Problem(C++)Day1

1000 - A+B Problem

大家好,这是我第一次上传

//今年我上初一下册

A+B的代码

题目:

1000 - A+B Problem
输入两个数字，输出它们之和
Input
一行两个数字A,B(0<=A,B<100)
Output
输出这两个数字之和
Examples//例子
input(输入)

1 2

output(输出)

3

Hint
Q: Where are the input and the output?
A: Your program shall always read input from stdin (Standard Input) and write output to stdout (Standard Output). For example, you can use ‘scanf’ in C or ‘cin’ in C++ to read from stdin, and use ‘printf’ in C or ‘cout’ in C++ to write to stdout. You shall not output any extra data to standard output other than that required by the problem, otherwise you will get a “Wrong Answer”. User programs are not allowed to open and read from/write to files. You will get a “Runtime Error” or a “Wrong Answer” if you try to do so. Here is a sample solution for problem 1000 using C++/G++:**

主要的框架

C++

#include<iostream>//最基础的

or

#include <bits/stdc++.h>//万能头文件

C++的

#include 
using namespace std;
int  main()
{
    int a,b;//申请a和b
    cin >> a >> b;//输入a和b
    cout << a+b << endl;//输出a+b
    return 0;
}

C/C++

#include <stdio.h>

int main()
{
    int a,b;
    scanf("%d %d",&a, &b);//各式对称,同上,只是指令不一样
    printf("%d\n",a+b);
    return 0;
}

PASCAL

program p1000(Input,Output); 
var 
  a,b:Integer; 
begin 
   Readln(a,b); 
   Writeln(a+b); 
end.

JAVA

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);
            }
}

老版JAVA

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);
    }
}
