Hangman C++ – 1st C++ Practice Assignment

In this article, we will implement a game of hangman c++. The game applies the following programming concepts in the language:

• STL Vectors
• Loops
• If/else statements

The hangman c++ code is documented clearly outlining how each block of code allows the game to function properly. If you are interested to get stuck in video game programming, I recommend the book “Beginning C++ through game programming“. With this book, you instantly start to get into programming games with C++ and it was one of the few resources I understood when I began with C++.
