Assignment 4 - Inheritance (M.I.L. method)

// Create a class called vehicle that has the manufacturer’s id and number of cylinders
// in the engine. Then, create a class called truck that is derived from vehicle and has the
// following additional proprieties (load capacity in tons (type double) and towing capacity
// in pound (type double)). Be sure that your class has constructor, setter and getter method.
// Write a program to test all your methods.
