Your goal is to implement an application that reads a file, modify its content, and writes the

modification back to the same file. The file includes 3 lines of integers. The first line indicates the

number of integers on the third line. The second line indicates which integer on the third line has been

selected (active). And the third line lists all the integers (maximum of 10).

Your application should have a menu that is constantly displayed on the screen (see the menu below).

Right below the menu, the program should display list of all integers in the file (third line). Also it

should show which integer is currently selected (active).

The user should be able to select a menu item by entering its associated key or by pressing one of the

indicated extended keys on the keyboard.

“Select Down” selects the next item in the list. If the last item is selected, this option selects the first

item in the list. “Select Up” selects the previous item in the list. If the first item is selected, this option

selects the last item in the list.

“Move Down” moves the selected item one position down. If the last item is selected, moving down

will not be possible. “Move Up” moves the selected item one position up. If the first item is selected,

moving up will not be possible.

“Insert” will insert an integer before the selected item and makes the newly inserted item active. The

integer is typed by the user. If the list is full, insertion will not be possible. Do not accept incorrect

values.

“Delete” deletes the active item.

“Sort” sorts the list in ascending order. The active item after the sort is same as the active item before

the sort.

“Jump from” changes the color of the active item so it can be moved to new location. “Jump to” moves

the colored item to new active location. “Cancel Jump” turns of the color and disables moving to new

location.

“Exit” ends the application.

Make sure to use the top-down design to break your program to many simpler tasks (at least one

function per task). Do not use global variables. Make sure to check the special cases. Example: list is

full or list is empty.

Your program should copy the content of the file into an array and variables when you start the

program. The program write back the content of the array and variables into the file when you exit the

program. When you are using the program, you should modify the array and variables and not the file.

Make sure to test your program completely before submission. Do not forget to add comments.
