C Projects Source Code - Snake Game
Published October 22, 2021In this c projects source code series we are going to create a simple Snake game with C Language. It is also a c console-based application, which is designed simply without using graphics. Snake Game Project is built for entertainment purposes like the Pacman game. The user gets a realistic feeling of playing the mobile snake game through this application.
The various coordinates in the screen have the food for the snake to eat, and when the snake eats food, it gains length by one element. The player gets their score increased according to the food that the snake consumes.
Three lives are given for the player, and when it is over the game will be terminated automatically
