C++ closely models rear world problem solving approach.C++ based on model of Object-Oriented Programming System.C++ is a methodology or paradigm to design a program using classes and objects. It simplifies software development and maintenance by providing some concepts: Object. Class. Inheritance

The main differently within the computer memory. A variable is a named location in memory that is used to hold A value that may be modified by program. All variable have to declare before they can be used.

void add : : get ( )
{
	cout << “Enter a no”;
	cin >> a >>b;
}
void add : : sum( )
{
	c= a+b;
}
void add : : show( )
{
	cout << “Numbers are = “<< a << “ “ << b;
	cout << “sum =” <<c;
}
void main( )
{
	add obj;
	obj. get( );
	obj.sum( );
	obj. show( );
	getch( );
