Basic Hello world program in C++

In this tutorial, we are going to see the basic hello world program in C++

#include<iostream>

using namespace std;

int main()

{

std::cout<<"hello world without namespaces"<<std::endl;

cout<<"hello world with namespaces"<<endl;

return 0;

}

___________________________________________________________________

OUTPUT:

hello world without namespaces hello world with namespaces

• As we can see in this program despite using any of the syntaxes we get the same output
• In the following tutorials, we are going to make use of the standard namespaces so that we do not have to write extra lines of code (std::)
