clrscr() is a custom extension introduced by MSC.

i already saw ur program.... u miss a curly braces after ur getch();.....
i solve 1 problem but wat is this "clrscr();" ??? it is clear screen ??? if it is ..... it should be system("cls");

>if it is ..... it should be system("cls");
No it shouldn't. Then you would add two problems to already nonportable code. If a screen clear is warranted, then it should be changed to something that the implementation supports, preferrably by doing something like this to make porting easier in the future:

void clear_screen()
{
  // Some nonportable solution similar to clrscr()
}

That way you can call clear_screen rather than the nonportable function and any changes are localized to that function.

Hi,
I do not understand, why are you using similar set of code time and again..???
Moreover, you have mixed the features of C & C++. Try making it an object oriented one if you are creating a .cpp file. Other problems have already been solved in previous replies.
