C语言项目：绽放的玫瑰花

剁手节已经过去几天了，当天成交量达到了恐怖的2000多亿，不知道大家贡献了多少呢？然而大家还有多少人记得双十一是光棍节呢？广大单身汪同胞还在苦苦挣扎，“大！家！不！要！慌！”今天就给大家带来一个绝佳的礼物，用来跟妹子表白，让大家早点脱离单身汪的生活。（感谢我吧，这可不容易哦~~~）

那么今天的神秘礼物是什么呢？大家猜猜送妹子什么最好呢？（送什么都不如送玫瑰花呀~~~）没错，今天给大家带来的就是一多缓慢绽放的玫瑰花！话不多说，先看图：

绽放的玫瑰，送给可爱的XXX

看起来是不是挺不错的呢！大家是不是觉得就结束了呢？ “当！然！不！是！”如果只有一朵花怎么能衬托出这中氛围呢？来首音乐才有情调嘛！然后我们再添加一首音乐！一边听着音乐，一边看着一朵玫瑰的绽放，是不是特有情调？（音乐不能截图，有需要的自己来找我吧）也许你就能从此告白成功，脱离单身，走向幸福的两人世界哦！（没成功当我没说(━┳━ _ ━┳━)）
