@ Justin: You forgot a space there. Also it's not quite what they are asking

@ OP: Are we working with a console? Because if that's the case you won't be able to delete an actual portion of the screen. You will need to redraw the whole thing, which isn't as hard as it seems. But before we got there can I get a little more detail? What are you trying to do?

i am asking the user to enter his name first.then asking him to enter his birhtplace.and then birthday....if the date entered is not valid(some thing like 43/6/2011,i want the user to re-enter his birthdaywithout proceeding next....i dont want to clear the screen at this moment nor do i want him to enter the previous data(ie name and birthplace)...i just want to clear the wrong date and not proceed untill the user enters a valid date

You'll have to gotoxy() the place you wish to overwrite, and write a bunch of spaces, then gotoxy() to that place again (where the user will give his answer).

Hope this helps.

thnx Duoas...it helped....now i am trying to understand your function

You only need the #included header and the topmost function, and all it does is call the Windows API function to set the cursor position on the console.
