3. After execution of the program, open the file to verify the information has been correctly written.
Program 2: The program provides a menu for the user to select different tasks. You can refer to the fig11_06.c, fig11_07.c for the read and write. Refer to the fig11_15.c for the design of the main function.
Description:
Option 1: the program reads all the data from the data file account.txt created in program 1 and display them on the screen. Write a function listAll() to finish this task.
Option 2: Add a new account and save the account information in the data file account.txt. Write a function newRecord() to finish the task.
Option 3: search for an account and display the information of the account. Write a function searchRecord() to finish this task.
Option 4: exit the program
The interface of the program is
Enter your choice
1 – list all account information
2 – add a new account and write to the datafile
3 – search for an account
4 – end program
