Corrections to errors in the existing files

[kvedala]

Description of Change

There are indeed a lot of corrections because of the errors that already exist in the repository.
This is a major effort to fix all the existing errors in the repository:

• wrongfully named
• non-compiling codes
• cpplint incompatible codes

There are a lot of files that changed and I already have a few auto-check tools that verify the CPPLINT and also compilation on linux, Windows and Mac operating systems. This can be checked here: https://github.com/kvedala/C-Plus-Plus/tree/cmake

Checklist

• Added description of change
• Added file name matches File name guidelines
• Added tests and example, test must pass
• Relevant documentation/comments is changed or added
• PR title follows semantic commit guidelines
• Search previous suggestions before making a new one, as yours may be a duplicate.
• Sort by alphabetical order
• I acknowledge that all my contributions will be made under the project's license.

Notes:

[kvedala]

@cclauss seems like the cpplint check tool is incorrectly linking the files: link
Instead of compiling and linking each file separately, it is incorrectly linking them all together. This is leading to duplicate references to functions like main

subprocess.CalledProcessError: Command '['g++', 'computer_oriented_statistical_methods/Gaussian_elimination.cpp', 'computer_oriented_statistical_methods/bisection_method.cpp', 'computer_oriented_statistical_methods/false-position.cpp', 'computer_oriented_statistical_methods/newton_raphson_method.cpp', 'computer_oriented_statistical_methods/secant_method.cpp', 'computer_oriented_statistical_methods/successive_approximation.cpp', 'math/fibonacci.cpp', 'math/prime_factorization.cpp', 'others/GCD_of_n_numbers.cpp', 'others/fibonacci_fast.cpp', 'others/matrix_exponentiation.cpp', 'others/pascal_triangle.cpp', 'sorting/shell_sort2.cpp']' returned non-zero exit status 1.

Too many files to review on one pull request. Can someone else please review?

There are a lot of existing errors in the repository that need to be fixed.
This is a major initiative to normalizaing these corrections 😓
