// Program name:  Concrete

// Win32 console application to satisfy programming test requirement

// for Chapter 3.



// Write a program to compute the cost of concrete for pouring a 

// basketball court.  Price should be a constant in the program.

// The programmer has a choice as to whether to make the depth of

// the concrete a constant.  The depth of the concrete is to be 4

// inches.  The user should be prompted to enter the length and 

// width of the court.
