Example 1: Data Types in C++

Data types in c++
	Built-in                User Defined            Derived
    ----------              -----------             ------------

    double, bool,		    enum,					pointer,
    long long			    class,					reference
    Wide Character		    typedef

Example 2: All data types in C++

Data Type 										Size
int (Integer) = 5, 6, 7							2
float (Floating Value) = -3.67, 2.67			4
double (Double of float) = -7.8746				8
char (Character) = 	'a', 'b', 'A'				1
string (Multiple chars) = "Hello World" 		No of Chars
