Certificate Printing, C++ (gcc)

Certificate Printing

/*
** Certificate printing**
Certificates are being printed with the names of two people in a team. 
To make the certificate look balanced, the person with the shorter name should be shown first. 
Write a program that reads in two names, and prints the shorter name first. 
If they are the same length, then they should be printed in the order they were typed in. 
The length is based on the number of characters in the name.
