怎么用C語言實(shí)現(xiàn)學(xué)生宿舍管理系統(tǒng)

這篇文章主要講解了“怎么用C語言實(shí)現(xiàn)學(xué)生宿舍管理系統(tǒng)”，文中的講解內(nèi)容簡(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“怎么用C語言實(shí)現(xiàn)學(xué)生宿舍管理系統(tǒng)”吧！

實(shí)現(xiàn)簡(jiǎn)單的學(xué)生宿舍基本信息管理，宿舍的基本信息包括樓號(hào)、房間號(hào)、面積、所容納人數(shù)、已入住人數(shù)等，系統(tǒng)以文本菜單形式工作。
