池塘夜降彩色雨的實現(xiàn)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上這是池塘夜降彩色雨的c語言代碼實現(xiàn)，由于用的是c語言的圖形庫，所以不能在vc6.0環(huán)境下編譯，要用c語言的編譯器，運行后只需輸入屏幕單位時間內(nèi)有多少個雨點和雨點下降的速度就可以運行！速度0-20 雨點20-40 自己可以看看代碼#include <stdio.h>#include <stdlib.h>#include <conio.h>#include <time.h>#include <dos.h>#include <graphics.h>#define LEN sizeof(struct ra
