Develop a class Point. A point is represented by $3$ coordinates: $x,y,$ and $z.$ The class must provide

the following functions:

translate $($int d$,$ char axis$).d$ is the distance the point will move in the given axis. axis can have one

of the following $3$ values: $\text{'}x\text{'},\text{'}y\text{'},$ and $\text{'}z\text{'}.$ If any other value is given, the function should do nothing

and return $-1.$ If an invalid value is given for d$,$ the function should do nothing and return $-2.$ Invalid

values for $d$ could be anything other than an integer value. The function returns $0$ if everything is

valid and the point is translated.

Develop a class Triangle. A triangle consists of $3$ Points. In the implementation of the attributes of

the triangle class, you must represent the three points as pointers to Point. You may name them

vertex$\_1,$ vertex$\_2,$ and vertex$\_3.$

Implement a method translate $($int d$,$ char axis$)$ that translates the three vertices of the triangle by d

in the direction of the given axis.

Implement a function to calculate the area of the triangle. Name it calcArea$().$ You decide its return

type.

Develop a constructor that takes three points as parameters.

Develop a default constructor that sets the three pointers to the three points to null.

Feel free to add any other functions that you see fit. Maybe a display function in Point or

Triangle??!! You decide $3.$

Both the Point class and the Triangle class must have destructors.

Develop a driver class that allows the user to create a triangle and to translate the triangle. You

need to provide a menu option to display the triangle coordinates on the screen.
