C++

A Scheme program that computes the Area of a Circle given the radius is quite small

A C program for computing the Area of a Circle is somewhat longer.

And a C++ program for computing the Area of a Circle is longer still.

In Scheme, we can make this program "nicer" by defining a procedure called square, and then using it in the AreaOfCircle program.

Similarly, we can define a define a procedure square in our C++ Area of a Circle program.
