Writing c++ program

Introduction:
                 
                    The source  code of a c++ program is stored on the disk with file extension cpp (cpp stands for  c plus plus)

Structure of c++ programs:
                     
                               A c++ program consists of three main parts:
  1.  Preprocessor Directive    
  2. The main() function
  3. c++ statements
Preprocessor Directives:
                                       The instructions that are given to the compiler before the beginning of the actual program is called Preprocessor Directives also known  as compiler Directives

Example:
         
#include<iostream>

using namespace std;

main()

{

   cout<<"<<Life is beautiful";

}

Data types in c++

DATA TYPES IN C++:                                        The variable  type specifies the type of the data that can be stored in it. Each variable is declared by its types.            c++ have five basic data types.These data type are:  int                               Integer float                             Floating point double                         Double Precision char                             Characters bool                             Boolean                          The first four data types are also available in c language.The bool is data type a new addition in c++ THE int DATA TYPE:                                         the int represents the integer data.It is used to declare integer type variables.                                    An integer is a whole number,i.e a number without a fraction or a decimal point.For example,645,230,-8 and 501 are integers.                                     The range of values that can  be stored
