c語言設計管理系統
1. 用c語言設計一個學生管理系統
高二的時候，我自己寫過。現在在學其它的語言，就不獻丑了，在網上給你找到了，是網路文庫裡面的，直接復制過來的話，排版不對，你自己去看一下吧，完整的代碼。
名字就是《用C語言編寫的一個學生信息管理系統》
PS：寫這個，主要是用到C語言的鏈表，不難，只是有的時候，如果思路不清晰的話，容易寫錯，寫漏等等，如果不參考上面，而是你自己寫的話，建議先畫個大概的樹圖出來，再開始編吧。
純手工打的，幫到你的話，就採納吧。
2. c語言 設計一個銀行管理系統
功能：能夠輸入和查詢客戶存款取款記錄。在客戶文件中，每個客戶是一條記錄，包括編號、客戶姓名、支取密碼、客戶地址、客戶電話、賬戶總金額；在存取款文件中，每次存取款是一條記錄，包括編號、日期、類別、存取數目、經辦人。類別分為取款和存款兩種。本系統能夠輸入客戶存款或取款記錄；根據客戶姓名查詢存款和取款記錄。分步實施：1、初步完成總體設計，搭好框架，確定人機對話界面，確定函數個數；2、建立一個文件，輸入客戶的必要信息，能對文件進行顯示、輸入、修訂、刪除等。3、進一步要求：完成客戶姓名查詢存款和取款記錄，並能得到每次帳戶總金額。要求：1、用C語言實現系統；2、利用結構體數組實現信息的數據結構設計；3、系統的各個功能模塊要求用函數的形式實現；4、界面友好（良好的人機交互），程序加必要的注釋。課程設計實驗報告要求：1、預習報告：題目、課程設計任務、數據結構、程序的總體設計（演算法）、模塊劃分 。2、實驗總結報告：流程圖、主要源程序代碼（需列印）、測試情況及調試中問題與解決方案、小結等要求：標明所用函數的用途和目的，簡單敘述製作思路。
是否可以解決您的問題？

6. C語言程序 如何編寫管理系統
C語言編程的規則
C語言源程序的編程語法歸納如下:
1,強制性規則
1,一個C語言源程序必須有且只有一個MAIN函數.
2,函數名後必須緊跟圓括弧對,函數體放在右圓括弧")"後的花括弧對"{}"中.
3,每個程序體(包括函數的函數體,含有多條語句的選擇結構和循環結構中的語句序列)必須用一對花括弧括起來.
4,文件包含預處理命令,#INCLUDE<*.H應置於源程序的開始位置.
5,語句未尾必須有分號,而預處理命令和函數首部的未尾及右花括弧之後不要分號.
6,同一字母大,小寫意義不同,關鍵字和標准庫函數名必須用小寫.
7,變數必須先定義,後使用
8,除已有明顯間隔符外,標識符,關鍵字之間必須有至少一個空格9,註解必須包含在"/* */符號之間
