Snake game using c programming mini project

This Mini Project ( Snake game ) is a simple console software with no graphics in C Snake Play. You can play the popular Snake Game in this project just like you've played it somewhere else. To push the snake you must use the up, down, right or left arrows.

Food is provided for the snake to eat at the various screen co-ordinates. Each time the snake eats the food, along with the score, its length will increase by one element.

Snake Game source code in C is complete and fully error-free. In Code::blocks it is compiled using the compiler gcc. The code is about 550 lines; Source code plus program file can be downloaded directly.

Functions used in Snake Game Project in C:

This Snake mini project used many features. I'll just list them below and describe the "gotoxy," "GotoXY" and "delay" functions as they are some of the most important features used in this and many mini projects in C.

  • void record()
  • void load()
  • void Delay(long double)
  • void Move()
  • void Food()
  • void Bend()
  • int Score()
  • void Boarder()
  • void Down()
  • void Left()
  • void Right()
  • void ExitGame()

void gotoxy (int x, int y) :

You need to understand this feature since it is one of the most relevant that is used in the Snake Game in C mini project. This functionality helps you to print text anywhere in your machine. Using this function in Code::blocks requires coding but can be used directly in Turbo C. Code::blocks provides this function with a code.

COORD coord = {0, 0};  // sets coordinates to (0,0) as global variables
void gotoxy (int x, int y)
{
        coord.X = x; coord.Y = y; // X and Y are the coordinates
        SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

Here, COORD coord= {0,0}; is a global variable. It sets axis center to the screen's top left corner.

void GotoXY (int x, int y)

Here is the code for this function in Code::Blocks.

void GotoXY(int x, int y)
{
    HANDLE a;
    COORD b;
    fflush(stdout);
    b.X = x;
    b.Y = y;
    a = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleCursorPosition(a,b);
}

This mini project in game C Snake gives users three lifetimes to play the game. The life-count is decreasing as the snake hits the wall or its own body. You can even pause the game in the middle of this mini project by pressing any key, and you can press any key to play again.

To sum up, this mini project on Snake game in C enables you to record the name of the player and the corresponding score you have obtained. For this reason the handling of files was used.

This mini project will definitely help if you're looking for a reference project, or you're looking to create your own C mini project game.
