1.Topic requirements

“Write a simple text editor using the list ADT (Problem P-6.3, Textbook, page 266).”

2 Program operation

1 Basic structure

2 Results

a Start the program

- Before input

- After input string :”bachkhoahochiminh”

b Left, right

- Before operation

- After press right arrow key:

-After press left arrow key :

c Delete

- Before operation( cursor position at the last character)

- After operation ( we deleted “hochiminh” from the previous sting)

d Insert

- Before operation

- After operation (we inserted “hochiminh2020”)

e Load previous sting

- Before operation

- After operation

3 Program source code

1 Library, function, and variable declaration

2 Main() function

- The function ask for the users ‘s desired operation and implement it right after recieve the input In the case the input is invalid, the program will ask them to input it again

- In the third operation, the random file is input from the user so that we have to check whether the program can open that file or not If not, an announcement will be displayed and user will have to input it again The variable “o” is use for this purpose while o = 0 mean no file are currently opened and o = 1 mean a file is opened

4 Kb() function

5 Read() function

6 Print() function

8 Insert() function

10 Save() function
