A+B Problem题解

新用户强烈建议阅读此帖

首先我们要理清思路

1.需要用到什么样的头文件？

2.用什么样的数据范围？

3.思路是什么？

首先题目中的数据范围是1≤a,b≤10^6, 而int 的范围是-2147483648-2147483647 正合题意，所以数据类型可以用int

话不多说，直接上代码

#include<iostream>//导入头文件，iostream里面是标准输入输出流（我说的什么？） 
using namespace std;//使用标准命名空间 
int main(){//主函数，程序的入口 
	int a,b;//创建a,b两个整型变量 
	cin>>a>>b;//输入 a , b 两个变量 
	cout<<a+b; //输出a+b的内容 
	return 0; 
}

本蒟蒻发的第一篇题解，请多多支持喵~~
