The modifications are as follows:

1. Increase the number of enemy aircraft

2. Speed up enemy aircraft generation

3. The plane can move up and down

Code Analysis:

1. Define the function first

2. Define function type, screen width, speed, enemy plane density, score, death int scr[22][n]={0},pl=9,width=24,speed=3,density=30,score=0,death=0; This program uses the shaping int.
3. Control the aircraft's movement coordinates: Enter a: The aircraft moves one cell to the left on the x-axis. Input d: The plane moves to the right of the x-axis, enter Q: The plane moves on the y-axis one grid, enter E: The plane moves down the y-axis, W is the position of the bullet, the initial position in the aircraft position on the Y axis to reduce a lattice.
4. Bonus Rule of death: if the coordinates of the bullet are the same as the Y value of the enemy plane, a bullet hits the enemy plane, plus points. In contrast, the coordinates of the enemy plane and the coordinates of the Y-value of the same, X-value difference one of my machine died.
5. Critical Position: Limited in the coordinate area the screen size cannot be exceeded.
6. Set the interface size of the aircraft speed, enemy aircraft density and control the direction of the key.
