In this easy application we be aware some factors listed. The line numbers are used for reference solely and are no longer phase of the application code.
Line 1: this is recognized as a pre-processor directive.
Line 3: Every C++ software ought to have a approach regarded as main(). It is referred to as the entry factor for the software when you begin execution of the application on your computer.
Line 4: Method our bodies in C++ begin with an open curly brace.
