我這有個答辯的程式，但是基本搞不懂，明天期末答辯，求高手分步驟詳解。
本人不勝感激啊

在線等
uj5u.com熱心網友回復：
這是dos下畫圖程式，沒有什么復雜的邏輯main()
{
int driver=VGA,mode=VGAHI;
initgraph(&driver,&mode,"C:\\TC"); //初始化圖形系統
cleardevice(); //清除圖形
hua(450,90); //畫花，上面的函式，主要由畫橢圓和直線組成
;setcolor(10); //設定顏色
rectangle(0,0,639,479); //畫外框
getch(); //接收按鍵
closegraph(); //關閉圖形系統
}
這個程式不難，主要是樓主上課不好好聽講
uj5u.com熱心網友回復：
就是首先定義了一個elli函式畫旋轉的橢圓，然后呼叫這個函式還有標準的橢圓、直線等函式畫出一朵花的各個部分，最終組成一朵花轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/118598.html
