preface
This is a small project written in c in my freshman year, "the implementation of Internet cafe management system", which is provided for everyone to learn and use here
Main knowledge:
- Creation and use of linked list
- File operation
- Application of various c statements
tips: when using, remember to add an Account library.txt document to the c file
1, Design task
Nowadays, the network is very developed, and various software, games and media have very high requirements for the network. Therefore, in order to meet consumers, Internet cafes must be rebuilt to establish an entertainment and management platform supported by network technology, computer technology and modern information technology, and develop the current activities based on game network to the platform of multi-functional entertainment, It will not only greatly improve the competitiveness and profitability of Internet cafes, but also build them into first-class high-end Internet cafes, so as to attract high-end consumer groups and lay a strong foundation for Liu. This is what we want to achieve. Therefore, it is analyzed that a reasonable, simple and standardized Internet cafe management system meets the current demand situation.
2, Programming and Implementation
This program is for two types of users, VIPs and administrators. There are two entrances. VIPs can register and log in. Administrators have fixed accounts and passwords (secret entrances). VIP has the functions of getting on and off the computer and changing password
Administrators have successively developed functions such as viewing and recharging member information. As shown in the figure below
1. Data description
(1) Member information storage
typedef struct
{
char vipAccount[MAX]; //Membership account (ID number)
char vipPassword[MIN]; //Member password
char vipPhoneNum[11]; //Member binding mobile number
int vipAmount; //Remaining amount of member
} VIP;
(2) Time information storage
typedef struct clock
{
int hour; hour
int minute; minute
int second; second
}Clock;
(3) Global variable design
Define global variables MAX and MIN to limit the length of account and password

Algorithm description:
3, UI design effect
1. Launch interface: a simple approach animation.
2. Start interface: display several functions.
3. User interface: basic information of members.
4. Information printing interface:
5. Deficiencies and corrective measures of the project so far:
(1) The interface display is not beautiful enough.
(2) Data printing is not neat enough.
(3) Failed to complete the function of playing games while timing (adding c language games in it) (I can't solve it now as a sophomore. My freshman intention is to use some small games written in c)
4, Code implementation (remember to add an Account library.txt text document)
tips: administrator system entry method: enter "administrator login" under the user menu. The default account is (account: admin Password: 1111)
Viewing method of verification code: open c file -- > open vercode.txt
User registration: ID is ID number, initial password: 123456 (modifiable)
