C program for Snake game
Snake Game is mini project in a C language. It is console application without graphic library that’s why it is more interesting.
This game is perfect without any error and better user interface.
It is complied in code block using c language.
Here goes a source code you can copy and compiled it in code block.
We hope it can help and become a reference for your project
