用类和easyx画一把枪

好的，以下是我为您提供的类和easyx画一把枪的代码：

#include <graphics.h>
#include <cmath>

class Gun {
private:
    int x, y, length, thickness;
    COLORREF color;
public:
    Gun(int x_, int y_, int length_, int thickness_, COLORREF color_)
        : x(x_), y(y_), length(length_), thickness(thickness_), color(color_) { }
    void draw() {
        setfillcolor(color);
        setlinecolor(color);
        setlinestyle(PS_SOLID, thickness);
        // 画枪管
        int barrel_length = length / 2;
        int barrel_x = x + barrel_length, barrel_y = y;
        line(x, y, barrel_x, barrel_y);
        // 画枪机
        int receiver_length = length / 4;
        int receiver_x = barrel_x + receiver_length, receiver_y = barrel_y - thickness / 2;
        rectangle(barrel_x, barrel_y - thickness / 2, receiver_x, barrel_y + thickness / 2);
        // 画枪托
        int stock_length = length / 3;
        int stock_x = receiver_x + stock_length, stock_y = y;
        rectangle(receiver_x, receiver_y, stock_x, stock_y + thickness);
        // 画枪口
        int muzzle_length = barrel_length / 2;
        int muzzle_x = barrel_x + muzzle_length * cos(30), muzzle_y = barrel_y - muzzle_length * sin(30);
        line(barrel_x, barrel_y, muzzle_x, muzzle_y);
        line(muzzle_x, muzzle_y, barrel_x + muzzle_length * sin(30), barrel_y + muzzle_length * cos(30));
    }
};

int main() {
    initgraph(640, 480);
    Gun gun(320, 240, 200, 8, RGB(255, 255, 255));
    gun.draw();
    getch();
    closegraph();
    return 0;
}

以上代码使用了Gun类，表示一把枪，通过构造函数传入枪的位置、大小、颜色等参数，通过draw函数绘制出枪的形状。在main函数中创建了一把枪，然后调用其draw函数进行绘制。
