Issue Title: Create Hangman Game using C++

Issue Description

I propose to develop a Hangman Game in C++ for this repository. Hangman is a classic word-guessing game that provides an entertaining and interactive experience for users. Implementing it in C++ will offer an opportunity to enhance the project's collection of C++ programs and create an engaging game for the community.
