Simple text editor in c++

C++

You will make a simple line-by-line text editor. Each page contains 20 lines and each line contains up to 100 characters. You may have up to 1,000 pages, while it starts from only 1 page and adds more pages when user types in. Each page has to be dynamically created when needed. Create a Page class and the Editor class can create an array of 1000 pointers to the Page class during the construction of the Editor class. (Actual page should be constructed when a new page is added)
At each time, a page is displayed with page number on the top and the line numbers on the left side of each line. There is a command line at the bottom and it shows possible commands as shown below.
[commands: line number allows you to edit the line, „N‟ goes to next page, „P‟ goes to the previous page, „Dn‟ deletes the line n – D3 deletes line 3]____

Here's what I have done and not sure how to proceed from here:

const int MAX_LINE = 20;<br />
const int MAX_CHAR = 100;<br />
const int MAX_PAGES = 1000;<br />
class Page {<br />
char aPage[MAX_LINE][MAX_CHAR];<br />
public:<br />
void print();<br />
void edit();<br />
void edit_line(int i);<br />
void delete_line(int i);<br />
};<br />
typedef Page * PagePtr;<br />
class Editor {<br />
PagePtr *pages;<br />
int cur;<br />
int total;<br />
public:<br />
Editor();<br />
void show_commands();<br />
void display_cur_page();<br />
void next();<br />
void prev();<br />
void edit();<br />
};
