                                      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1a,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; 
                                      }
