i have this c code its a bouncing ball game and it has a paddle to make the ball bounce back but it is not working. how to fix it?

#include #include #include

// Define constants for the screen size and ball velocity. #define SCREEN_WIDTH 60 #define SCREEN_HEIGHT 20 #define BALL_VELOCITY 1 #define CENTER

// Variables to keep track of position and speed of ball int x = 0; int y = 100; int x_speed = 5; int y_speed = 5; // Variables to keep track of paddle int x_paddle = 250, y_paddle = 370; int paddle_width_half = 40; // score keeping int score = 0; int width; int key; int LEFT; int RIGHT; int keyPressed; int keyCode;

// Called every re-draw, defaul 30 times per second void draw() {

// Update position by adding speed x = x + x_speed; y = y + y_speed; if (y < 0) y_speed = -y_speed; if (x > width || x < 0) x_speed = -x_speed;

// Check if keys are pressed if (keyPressed) { if (keyCode == RIGHT || key == 'd') { // Move paddle right x_paddle = x_paddle + 8; } else if (keyCode == LEFT || key == 'a') { // Move paddle left x_paddle = x_paddle - 8; } else if (key == ' ') { // Restart x = 0; y = 100; x_paddle = 250; score = 0; } } }

int main() {

// Initialize the random number generator. srand(time(NULL));

// Initialize the ball position and velocity. int ball_x = SCREEN_WIDTH / 2; int ball_y = 1; int ball_velocity_x = BALL_VELOCITY; int ball_velocity_y = BALL_VELOCITY;

// Game loop. while (1) { // Clear the screen. system("cls");

// Draw the ceiling. for (int i = 0; i < SCREEN_WIDTH + 2; i++) { printf("-"); } printf(" ");

// Draw the ball. for (int i = 0; i < ball_y; i++) { printf(" "); } for (int i = 0; i < ball_x; i++) { if (i == SCREEN_WIDTH / 2 - 3 || i == SCREEN_WIDTH / 2 + 2) { printf(" "); } else { printf(" "); } } printf("O ");

for (int i = ball_y + 1; i < SCREEN_HEIGHT; i++) { printf(" "); } for (int i = 0; i < SCREEN_WIDTH + 2; i++) { printf("_"); } printf(" ");

// Update the ball position and velocity. ball_x += ball_velocity_x; ball_y += ball_velocity_y;

if (ball_x == 0 || ball_x == SCREEN_WIDTH - 1) { ball_velocity_x = -ball_velocity_x; } if (ball_y == 0 || ball_y == SCREEN_HEIGHT - 1) { ball_velocity_y = -ball_velocity_y; }

// Check if the ball goes into the hole on top or bottom and make it come out as two balls. if (ball_x == SCREEN_WIDTH / 2 - 2 && ball_y == 0) { ball_velocity_y = -ball_velocity_y; ball_y += ball_velocity_y; printf("OO "); } else if (ball_x == SCREEN_WIDTH / 2 - 2 && ball_y == SCREEN_HEIGHT - 1) { ball_velocity_y = -ball_velocity_y; ball_y += ball_velocity_y; printf("OO "); }

// Wait for a short time to control the game speed. for (int i = 0; i < 100000000; i++) { // Do nothing. } }

return 0; }
