Do you mean console, text console. Are you writing the pacman game on a console?! Well, this is possible, but why? Cross-platform, maybe?
Anyway, it is not related to "2D array" or something...

the problem is we are recommended to use only array or pointer data structure not even classes or graphics library....until now board is complete just like in youtube link and on each keyboard input complete broad is redisplayed .What i want to refresh that the board on console

Please see my comment to the question. If this is really a console, a text console in a standard console-only application type, there is no "refresh" or some usual even-oriented features. You should simply redraw the whole console "screen" again, the same way as you did it before modification of your data. However, it is always better to locate only the subset of the console points to be updated and redraw only the changed part.

The whole activity in a text console is pretty weird for these days and not really so simple. I would say, making a usual graphical game based on GDI+ or DirectX (or one of higher-level graphical UI frameworks, such as MDI, Qt, Gtk+) would be easier. However, developing such a game on a console-only application is quite possible.

Solution 2

In order to accomplish your task you might use the Console Functions[^] on Windows, and ncurses on Linux (see, for instance "NCURSES-Programming-HOWTO"[^].

Our teacher has strictly instructed us not use any graphics library or 3rd party api .We are taught C++ until array so we are bound to use until array....

If you can use only C++ iostream then you have to do what already suggested by Sergey: rewrite the entire screen (that is the whole array) on each (even minimum) change.

If you are using Windows the console functions as suggested should conform with your teachers requirement as they are neither a graphics library or 3rd party api. Perhaps you should check. There is plenty on the web about game programming using the console functions to do exactly what you are asking.

It also seems a reasonable question so the downvoting is puzzling.

5ed. However, what OP does can make some sense: the study.
