C language student management system (open source)

The freshman class is designed to — A not so bad C Language student management system ( Attached report )

It was so beautiful when I was a freshman , At that time, I didn't feel tired after staying up late to write for a week in order to realize a project , On the contrary, I was very excited after finishing the project alone , There is an unspeakable sense of joy , I really admire myself at that time , One person is making trouble 2000 Many lines of code , But it's a good thing that I made a billion comments at the beginning , Otherwise, I can't understand it now , The code part is tedious , But I still haven't changed , After all, it was also the painstaking efforts of that year .

If you haven't been learning for a long time , My advice is not to pursue fancy interfaces , Don't even think about copying online game algorithms , It doesn't work , What you need to do is to be familiar with the use of data structures , Cultivate the thinking of project engineering , Can put the c The pointer can be used flexibly without memory leakage , Innovative design , This is the best , Many other similar projects on the Internet are flashy , Not very suitable , This project is pure c Language writing , There are hardly any global variables , The pointer is very flexible , The memory is also released manually when exiting , It also uses a powerful data structure , Handwriting input function , Ask you to correct the pointer 、 Array 、 data structure 、 Various functions are skillfully mastered , It can consolidate your knowledge , If I can help you , You might as well click "like" to support ！

Besides , This project has been tested by dozens of people before and after , Have been put forward n individual bug, But they have all been modified , Several versions have been updated ( The price is a little messy ), Resisted the teacher's questions and tests , And succeeded in getting 99 Point high score , It should be said that it is a fairly good freshman course

Basic function

1. Realized the account login system , Realized the operation of login and password modification .
2. Realize file reading and writing , The content stored in each account is unique , Read and write from file , And save to file .
3. It implements custom input , utilize getch Function custom input function , Pop up prompt for out of range input , Pop up prompt for illegal input , For password input *** The way
4. The basic data maintenance is realized , That is, increase , modify , Delete , Inquire about , And all the functions have good human-computer interaction .
5. The achievement of a single subject query , And a summary report on the results of each subject , Innovative design .

For those who improve their programming , The quickest way is to do it , You can learn from this project , You can also take it with you , This can greatly enhance your programming ability , Of course, you can modify it a little , As your lesson plan ！

You know - Student management system demonstration video

At the end of the paper, the open source code is given .

Run time screenshot ：

Bright spot ：

1. As a freshman, the class is designed to , A lot of code , There are two subsystems in a system , Code super 2000 Multiple lines ( Although now I see this code, I think it has written a lot of nonsense )

2. It has relatively perfect human-computer interaction function , Basically, I have set the function of return and continue operation for each operation , Give users a better experience

3. The login mode is adopted , Allow password changes , Single account data is stored in the file

4. Powerful data structure , The student information management system uses a AVL Binary tree , The student achievement system adopts two-way multi linked list maintenance , Better reflect their own level

5. Functional perfection , Innovative design

6. Code modularization , Classification defines header files and source files , Almost no global variables are used , Although it may be complicated to transfer parameters , But make the project modular , More readable

7. Custom input , This makes it possible to detect errors in user input , For example, characters are not allowed when entering numbers , And there are scope provisions .

Header file and function definition ：

1.FileO,h&&FileO.c, This module is designed for login and many file operations (File Operate)

2.Core1.h&&Core1.c, This module designs the core operation related to the student information management system

3.Core2.h&&Core2.c, This module designs the core operation related to the student achievement management system

4.Input.h&&Input.c, This module customizes the input , Make all inputs use getch( stay vs I don't support , It needs to be replaced with _gettch_), So that whether the input is valid or not can be determined at the time of input

5.ShowMap.h&&ShowMap.c, This module designs functions related to the interface

When reading the code, it is recommended to read the large operation manual first , Understand specific program modules , Then it is recommended to read the header file , There are definitions of various functions and they are annotated , You can basically understand the general functions .

Some other questions

Some small partners find that removing the function declaration in the header file can also run , Yes , Yes. ,cb The link to is very strong , But this is an engineering idea .

Count on VS It must be troublesome to run ,VS Environment and CB Is different .DEV I don't know , However, the following compilation options must be changed .

It seems that there are many small partners who give feedback on what will happen for-loop… error , This is the issue of compilation options , stay c99 It was not allowed to for Of variables defined in , So you should adjust the compilation environment to the latest c11 or c99 standard . Here's how ：

1. find setting, Click on Compiler…
2. Compiler settings Flag（ Remember to point ok）
3. Add compilation parameters to other options ( Remember to point ok)
