Specific instructions for lab 05

This lab requires that you implement doctest based tests. There is already a skeleton Makefile with targets for main and tests as well as skeleton .c .h and doctest.h files.

Task A

For task A, write the function using the prototype void test_ascii() in funcs.cpp / funcs.h. It should be called from main and should not be tested via doctest from tests.cpp.

Task B

Add files caesar,cpp and caesar.h to your program. In them, write the two functions specified in the main lab.

These two functions should be tested via doctest form tests.cpp.

Task C

Add files viginere.cpp and ~viginere.h to your program. In them, write the function specified in the main lab. This should also be tested via doctest from tests.cpp.

Task D

Add files decrypt.cpp and decrypt.h to your program and in them implement the functions specified in the main lab. These should also be tested via doctest and should not require any keyboard input when the program is run.

Notes

I will test main but will only consider tests.cpp to determine if your functions area all working properly. You will have to make sensible decisions based on the assignment as to how many tests you need and what you should test for.

You will have to determine what to test and how many tests are sufficient. Also, tests should not require keyboard input. Test values should be hard coded.

For reference, the doctest package and documentation can be found here.

Note: Remember that your program (including tests) should not ask for any keyboard input. When run it should clearly show that all tasks are implemented and work.
