C语言绘制表白玫瑰花操作步骤及源码

C语言绘制表白玫瑰花操作步骤及源码并不只看表面做法，关键还要理解相关条件、限制和后续影响。

一、项目介绍

这是一个用C语言绘制的表白玫瑰花图形。

玫瑰花象征爱情和真挚纯洁的爱，爱情、和平、友谊、勇气和献身精神的化身，人们多把它作为爱情的信物。赶快把它送给你想送的人吧！

编译环境：visual c++ 6.0

第三方库：Easyx2022 注意需要提前安装easyX，如没有基础可以先了解easyX图形编程

二、运行截图

三、代码思路

1.引入easyx头文件

#include <easyx.h>

2.创建背景为亮蓝色的绘图窗口

initgraph(640, 480);setbkcolor(LIGHTBLUE);cleardevice();

3.定义全局变量

introsesize = 500;inth = -250;

4.定义结构体

struct DOT{double x;double y;double z;double r;double g;};

5.计算点

bool calc(double a, double b, double c, DOT& d){double j, n, o, w, z;......

完成
