*Motivation:* One of the main uses of computers in calculus is to
provide graphical description of different functions. The graphical
representation of a graph y = f(x) is formed by different points
with coordinates (x, y = f(x)).

*Task:*

1. Define a class *Point* in which each object has two real-valued
coordinates x and y. Do not forget to include a constructor, accessor
methods, and mutator methods.

2. In the main method,
define an array of 100 points, in which the
i-th point has coordinates x = i/100 and y = x^2.

3. Trace your code for the first two points, with x = 0 and y = 0, and with
x = 0.01 and y = 0.0001.

*Comment:* your code will be helpful in plotting a quadratic function
y = x^2.
