How to print Hello World

Today we will learn to print hello world in C++.First we would include the library iostream which has the cout which is needed to print.then we write int main() which is the function where we write the main code we need to run.The curly brackets are inside which we write our code. Then we write the cout command to print hello world.The semicolon represents the end of one line of code.As we used int main() the function requires us to return an integer so we use return 0.

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