C++: Address Book Management System
content
1. Functional requirements
3. System design
4. Code implementation
——————————————————————————————————————— ——————
*1. Functional requirements
- System page function selection display
- Add contact function
- Show contacts feature
- delete contact function
- Find contacts feature
- Edit contact function
- Clear contacts
- Exit the address book function
*2. System Design
- Use structure to represent - person; attributes are: contact name, gender, phone number, address;
- Use the structure to represent the address book; the attributes are: contacts, the number of contacts in the address book;
- use an array to store contacts;
- The while loop can realize the function of continuously entering the address book, and exit the loop if the address book is exited;
- Use switch for menu function selection;
*3. Code implementation
- break ends the loop and jumps out of the loop body;
- continue to end this loop and proceed to the next loop;
- return jumps out of the method where the loop body is located, which is equivalent to jumping out of the loop body
