[c++ question-002] hello, world problem

        Hi, everyone, I am here to explain the C++ topic to you again. The topic we are explaining today is the "hello, world" topic. This topic can be said to be the first lesson for every programmer.

        ​ ​ ​ First, let’s take a look at the requirements of this question:

It can be said that it is very simple, but I still have to tell you about the pitfalls in this process, because I have only been through it many times.

1. Try to copy its sample output, because you may not be able to see the capitalization, spaces and the like.

2. C++ has very strict requirements for ";", just like Python's requirements for indentation. It is very strict. Programmers who are coding for the first time, please pay attention.

Without further ado, here’s the code:

#include <iostream>
using namespace std;
int main(){
    cout<<"Hello,World!";
    return 0;
}

Among them, "return 0;" must be typed in the new C++ version. I hope everyone will pay attention to it. Today's article ends here. See you in the next issue! !
