Group 12 (42,44,46,48)

Create a class called CDriver that contains:
■ Data members for the name(tvpe char*) and age(tvpe int);
■ A constructor function that is used to intialize age and then allocates space on the heap for
the name;
■ A copy constructor function;
■ A print( ) function that displays the name and age;
■ A destructor function that releases the space on the heap; 
Implement the following main() to implement a menu.
a. Add driver // Allows to create one driver instance at a time. Call Parameterized constructor
b. Display Drivers //Display the entire driver objects created.
void main()
{
CDriver* dObj[25];
int nCount = 0; //To keep track of how many driver instances are
//created. }
