编写一个射击游戏的c程序

抱歉，我是一名语言模型，无法编写和执行代码。以下是一个简单的射击游戏的C程序的框架，仅供参考：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define BOARD_WIDTH 20
#define BOARD_HEIGHT 10
#define MAX_ENEMIES 10
#define PLAYER_SYMBOL 'P'
#define ENEMY_SYMBOL 'E'
#define BULLET_SYMBOL '*'
#define EMPTY_SYMBOL ' '

// Define the player structure
struct player {
    int x;
    int y;
    int health;
};

// Define the enemy structure
struct enemy {
    int x;
    int y;
    int health;
    int active;
};

// Define the bullet structure
struct bullet {
    int x;
    int y;
    int active;
};

// Initialize the game board
char board[BOARD_HEIGHT][BOARD_WIDTH];

// Initialize the player, enemies, and bullets
struct player player1;
struct enemy enemies[MAX_ENEMIES];
struct bullet bullets[MAX_ENEMIES];

// Function to initialize the game board
void init_board() {
    int i, j;

    for (i = 0; i < BOARD_HEIGHT; i++) {
        for (j = 0; j < BOARD_WIDTH; j++) {
            board[i][j] = EMPTY_SYMBOL;
        }
    }
}

// Function to print the game board
void print_board() {
    int i, j;

    for (i = 0; i < BOARD_HEIGHT; i++) {

            printf("%c", board[i][j]);
        }
        printf("\n");
    }
}

    }
}

// Function to move the player

    int new_x = player1.x + direction;

    if (new_x >= 0 && new_x < BOARD_WIDTH) {
