Your First C++ Program

The C++ compiler ignores blank lines.
In general, blank lines serve to improve the code's readability and structure. 
Whitespace, such as spaces, tabs, and newlines, is also ignored, although it is used to enhance the program's visual attractiveness.

#include <iostream>
using namespace std;

int main()
{
cout << "Hello world!";
return 0;
}Try It Yourself

In our code, the line using namespace std;tells the compiler to use the std (standard) namespace. 
The std namespace includes features of the C++ Standard Library.
