The above is a C language production of small game aircraft game code

In simple terms, a main function consisting of 5 sub-functions is then controlled by these 5 sub-functions to control the entire game.

Here is a brief summary of the 5 separate functions:

1. void print (int [][n]);//Output function

   This function is the backbone definition of the function that is the central axis of the entire function game

All of the function models are defined by the output function, such as the model of the enemy aircraft, model bullets, and so on.

and a border display.

2.void Movebul (int [][n]);//bullet Move function

This function is to control the movement of the bullets his principle is quite simple is a for statement from the bottom of the i--loop in connection with the output function to replace the model with bullets can be critical of this sentence

for (j=0;j<width;j++)

{

if (i==0&&a[i][j]==2)

a[i][j]=0;

if (a[i][j]==2)

{

if (a[i-1][j]==3)

score+=10,printf ("\7");

He's controlling the bullets moving and adding points when the bullet moves upwards, the original position a[i][j] becomes 0 and a space defined by print, and then the position is a[i+1][j] the axis moves up one to 2 and "." And there is the position of the enemy position with the coordinates of 1 o'clock Score+10

3.void movepla (int [][n]);//enemy Movement function

The same with 2 the only difference is death

4.void setting (void);//Set function

The set function is controlled by the character of the menu function and ESC is pressed to enter

Case "" Control interface size break; Go directly to the next option

Default is Enter printf ("Display error") when input is not related to case ""

5.void menu (void);//Menus function

The most basic meet by printf () Getche and if statement control is easy to understand
