C++實(shí)現(xiàn)班級通訊錄管理系統(tǒng)

設(shè)計流程
本系統(tǒng)基于C++實(shí)現(xiàn)班級通訊錄管理系統(tǒng)。功能包括增、刪、查、改等。通訊錄包括的個人信息有姓名、學(xué)號、性別、籍貫、政治面貌、手機(jī)號、QQ號、宿舍等。主要用到了指針、結(jié)構(gòu)體、遍歷鏈表、文件讀取等知識點(diǎn)。

優(yōu)點(diǎn)
1 . 此系統(tǒng)含有歡迎使用的頁面，之后進(jìn)入功能頁面。
2 . 功能設(shè)計根據(jù)實(shí)際情況設(shè)計能夠最大限度滿足現(xiàn)實(shí)需求。
3 . 界面簡潔易懂，操作簡單。
