Snake game in C++

Write a Program Snake game in C++

How to make a game in C++:

This game will be made using ‘C++’ programming language. We’ll be creating this game using the ‘Console Mode’ window. Here, we’re looking at how to play the game and also making the game more interesting by adding some more advanced codes.

What do you mean by the Snake game?

The C++ snake game is a great game that tests the coordination between your eyes, hands and the brain in such a unique and fun way. The game is inspired by the old classic video game called “snake”. To play the game, you need to control your snake with your hands and tilt your phone to avoid the obstacles. The goal is to gather as many eggs as possible and also destroy the eggs of your opponents.
