Fix [main readme.md for CPLUSPLUS]: several README.md links return 404

[fshitstack]

Proposed fix : change necessary files according to the required case convention

about 30 issues.

Ideally all should follow naming convention as in docs, but this issue focus only on dead links:

from the contributors handbook

Directory Naming The Repository follows a strict directory naming scheme i.e. capital case with underscores, e.g. Directory_Name. Auxiliary verbs, propositions, conjunctions, and other similar words should be in lower case (excluding the first word). Example: This_is_Directory. Contributors are requested to ensure that they are updating these README files with proper format, to maintain the aesthetics of the Repository.
