C语言实现飞机大战游戏

飞机大战游戏是一款经典的飞行射击游戏，可以用C语言实现。下面是一个简单的示例代码，可以用来实现基本的游戏功能：

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <Windows.h>

#define WIDTH 80
#define HEIGHT 30
#define MAX_ENEMIES 5
#define ENEMY_SPEED 2

typedef struct {
    int x, y, speed, alive;
} Enemy;

typedef struct {
    int x, y;
} Bullet;

void gotoxy(int x, int y) {
    COORD pos = {x, y};
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

void draw_ship(int x, int y) {
    gotoxy(x, y);
    printf("  /\\");
    gotoxy(x, y+1);
    printf("<###>");
    gotoxy(x, y+2);
    printf("  \\/");
}

void draw_bullet(Bullet bullet) {
    gotoxy(bullet.x, bullet.y);
    printf("|");
}

void draw_enemy(Enemy enemy) {
    if(enemy.alive) {
        gotoxy(enemy.x, enemy.y);
        printf("^");
    }
}

void update_bullet(Bullet *bullet) {
    bullet->y--;
}

void update_enemy(Enemy *enemy) {
    enemy->y += enemy->speed;
    if(enemy->y >= HEIGHT) {
        enemy->alive = 0;
    }
}

        (*num_bullets)++;
    }

该代码使用了Windows系统的控制台API，因此只能在Windows系统上运行。如果要在其他系统上运行，需要使用其他的图形库或框架。代码中使用了结构体来表示敌人和子弹对象，使用了循环来更新敌人和子弹的位置，使用了随机数来生成敌人对象。当敌人与玩家的飞机相撞或者子弹打中敌人时，会更新分数。当敌人撞到底部边界时，会消失。当玩家的飞机被敌人撞到时，游戏结束，显示最终分数。
