學(xué)生宿舍管理系統(tǒng)一設(shè)計(jì)內(nèi)容及要求：為宿舍管理人員編寫一個(gè)宿舍管理查詢軟件。要求：1)建立數(shù)據(jù)文件，數(shù)據(jù)文件按關(guān)鍵字(姓名，學(xué)號(hào)，房號(hào))進(jìn)行排序(冒泡，選擇，插入排序等任意一種)2)查詢菜單(用二分法實(shí)現(xiàn)以下操作)按姓名查詢按學(xué)號(hào)查詢按房號(hào)查詢二概要設(shè)計(jì)1)需要定義一個(gè)結(jié)構(gòu)體：typedefstructpnode/*結(jié)構(gòu)體定義用于存放學(xué)生信息的節(jié)點(diǎn)*/用來存儲(chǔ)學(xué)生的信息。2)create()/*初始條件：必須保證原有記錄是空時(shí)方可建立*/操作結(jié)果：建立一個(gè)新的數(shù)據(jù)文件3)readfile()/*初始條件：數(shù)據(jù)文件已經(jīng)建立*/操作結(jié)果：獲取次文件的信息serchl()按姓名查找serch2()按學(xué)號(hào)查找serch3()按宿舍號(hào)查找初始條件：數(shù)據(jù)文件中含有紀(jì)錄操作結(jié)果：不支持模糊查詢必須查詢項(xiàng)和關(guān)鍵字吻合情況下才可查詢。調(diào)用按不同關(guān)鍵字查詢的子函數(shù)若存在相應(yīng)的查詢結(jié)果則顯示在屏幕上，若查找的紀(jì)錄不存在則提示該紀(jì)錄不存在，請(qǐng)建立相應(yīng)的數(shù)據(jù)紀(jì)insert()/*添加數(shù)據(jù)紀(jì)錄的函數(shù)*/初始條件：必須已經(jīng)建立了數(shù)據(jù)文件操作結(jié)果：在數(shù)據(jù)文件中添加新的紀(jì)錄若沒有建立數(shù)據(jù)文件則添加失敗。delete()/*刪除數(shù)據(jù)紀(jì)錄的函數(shù)*/初始條件：必須建立了數(shù)據(jù)庫并且數(shù)據(jù)文件中含有數(shù)據(jù)紀(jì)錄操作結(jié)果：刪除輸入學(xué)號(hào)的學(xué)生的一切相關(guān)紀(jì)錄updata()/*修改數(shù)據(jù)紀(jì)錄的函數(shù)*/初始條件：必須建立了數(shù)據(jù)庫并且數(shù)據(jù)文件中含有數(shù)據(jù)紀(jì)錄

操作結(jié)果：修改輸入的學(xué)號(hào)相對(duì)應(yīng)的學(xué)生的一切信息。如不存在相應(yīng)的紀(jì)錄則提示不存在8）output（）/*輸出函數(shù)*/初始條件：數(shù)據(jù)文件已經(jīng)建立操作結(jié)果：起泡法排序按學(xué)號(hào)順序輸出記錄2>本程序包含10個(gè)函數(shù)：1.
