This is a simple issue of a + b, c ++ application knowledge, someone asked why not universal header files, because some do not recognize it, or why I do it?

Here is the code:

#include<iostream>
using namespace std;
int main()
{
	int a;
	cin>>a;//输入a 
	int b;
	cin>>b;//输入b 
	cout<<a+b/*将a,b相加*/<<endl;
	return 0;
}
/*也可以这样写*/ 
/*{	long long a,b;
	cin>>a;
	cin>>b;
}

Then remember the point of praise ah!
