The program has a DNA_Strand.h. file that contains the declaration of a set of functions to manipulate static arrays representing DNA. The job is to use a test program to thoroughly test the DNA_Strand class to ensure it works as expected. The DNA_Strand.h. file describes all the public functions that need to be tested.
