Snake-Game/ Snake

Snake is the common name for a video game concept where the player maneuvers a line which grows in length, with the line itself being a primary obstacle. The concept originated in the 1976 arcade game Blockade, and the ease of implementing Snake has led to hundreds of versions (some of which have the word snake or worm in the title) for many platforms. After a variant was preloaded on Nokia mobile phones in 1998, there was a resurgence of interest in the snake concept as it found a larger audience.

Project Tree

snake.h - Contains all the function and variables declaration which are used by all the files. It also contains:
- struct body - The body segment of snake.
- class snake - A whole single snake.
class_snake.cpp - Contains definitions of functions of class snake.
functions.cpp - Contains definitions of functions used in main.cpp. Those functions are either declared in main.cpp or snake.h.
main.cpp - The actual logic of forming window, signal handling, printing, etc, is written here.

How snake works?

The division of snake body into segments is explained in snake.h.

Now let's assume b_n means n^th body segment. Then linked list of snake, with 2 body segments, looks like:

tail ----> b₂ ----> b₁ ----> head
