This is a program that computes clothing sizes by age, weight, and
height. However I am unable to get the program to display the results. I
fear I may have the code arranged wrongly or I might be missing a
declaration, but I believe the main problem is calling the methods to the
output string. Any advice would be greatly appreciated. Thanks.
