Question

(project 4)Write a class for an airplane class with constructors, interface (mutators and accessors)and a test driver (main). It should be able to change altitude (up,down) and speed.

The default constructor will set the altitude to 0 and speed to zero and longitude and latitude

to Boston, Massachusetts (42.3631 degrees N, 71.0064 degrees W). The overloaded constructor will set longitude and latitude to Louis Armstrong (29.9933 degrees N, 90.2581 degrees W) by passing that string to the Airplane object when it is created. If the altutude ever falls below 0 the change altutude function should announce the plane had crashed and the program exit as in the previous project. All mutators and constructor should check input for >= 0 ( no negative speeds or altitudes).

(project 5)(read the above first)

Add an external boolean equals() function that takes in two objects and returns true if they have same latlong and altitude. Write code to test it that announces a crash it equal.

Add external equalsto()function that takes in two objects and returns true if they have same latlong and altitude. The equalsto() functions is a friend function and has direct access to altitude and latlong. The objects are pass-by-reference. Write the most efficient function you can (change to pass by reference?).
