Improve cpp exercises READMEs with function name to implement

[RiccardoBuscicchio]

Hi all,
while going through the cpp track I noticed that a few exercises README.md provide incomplete instructions.

The exercises can frequently be completed inspecting the corresponding *_test.cpp, e.g. looking for the specific function name that the user is required to define. E.g., these are the ones I have found out of the 15 I have gone through so far.

• https://exercism.org/tracks/cpp/exercises/leap
• https://exercism.org/tracks/cpp/exercises/raindrops
• https://exercism.org/tracks/cpp/exercises/difference-of-squares
• https://exercism.org/tracks/cpp/exercises/atbash-cipher
• https://exercism.org/tracks/cpp/exercises/trinary

I would like to use the opportunity of going through the exercises to spot and amend those affected.
Would you be interested in a PR on this?

Hello @RiccardoBuscicchio,

welcome to Exercism. I am happy to hear that you enjoy the C++ track and want to improve it.

Your ideas have been discussed several times on the forum. This post is the most recent example. I think the explanation of the current procedure by Siebenschläfer is pretty interesting.

Feel free to add to the discussion!
