Could you please edit your post and use the forum [code] tags? It will help us be able to read it, thanks.

What is the t.cpp file that is referenced on line 21?

[Bazzy]

1. Read http://www.cplusplus.com/articles/how_to_ask/
2. Use [code][/code] tags
3. that looks pre-standard C++
4.

ERROR 1-error: conio.h: No such file or directory

conio.h isn't a standard header

ERROR 2-error: process.h: No such file or directory

nor is process.h

error: 'getch' was not declared in this scope

getch is from conio which isn't standard

[sukhi]

so ... wat changes do i make in da program....? i'm in a situation here.got very little time left.can someone please make the required corrections and post it again.please. :(

[kevinkjt2000]

iomanip.h is not standard either...
I suggest using standard libraries and getting rid of nonstandard commands like getch as Bazzy suggested.

[Bazzy]

iomanip.h is not standard either...

iomanip is standard: http://www.cplusplus.com/reference/iostream/manipulators/
( except for that old-style .h )

[gcampton]

wat changes do i make in da program....?

If you want to take the advice, then simply remove the conio.h, What methods are you using in it? prehaps we can tell you what you can use instead if you can describe what they do ?

Because I can garuntee that pretty much nobody here will be familar with conio.h, or process.h.

So you need to tell us what methods they use, and what the method does.

[tummychow]

No way in hell should anybody be

make the required corrections and post it again

. The point is to give you help, not the answer. Bazzy already directed you to how to ask.
Anyway, I second gcampton; conio and process are both deprecated (heck, I don't even recognize process). Take them both out, get rid of getch and any crap from process, and that should solve most of the problems.
Also, istream.get() does not return a character. You pass the object you want your input to go into; get returns a reference to the istream against which it was called (this).
Besides that I don't see any errors. So that's probably it, unless there are things you didn't mark out on that code.

[sukhi]

k... i'm sorry about the "corrections" part of my previous statement...
and thanks for the help.

[gcampton]

I assume clrscr();
clears the screen ? 1 example you could do instead of this is simply print 10-20 blank lines. However it's usually bad form to mess with consoles in this way. They are not really necessary, it's fine to be able to scroll up and see what the program has done, it also helps debug errors.

Oh...

Just saw this:
clrscr();
window(1,1,80,25);
textcolor(BLACK+BLINK);
gotoxy(30,1);
cprintf("[DELETION]");

I didn't realize this was a window application, I assumed it was console. your going to need to read up on Windows API if you prefer MS windows, or something x-compatible QT, wxWidgets. etc.
You could read through some posts on the windows forum to find the references you need.
============================================
The other way you could go is trying to get those 2 header files into your project, your going to have to search your computer for them, or download them and put them into your library path.

[kevinkjt2000]

You are right Bazzy I should have been more specific he probably does not know that the .h ones are old.
Man I hope if he does learn some Windows API, he will at least follow everyone's advice and not use the older unknown/ non-standard functions like getch.

[unoriginal]

It looks like some old code you got somewhere around the internet or some book after searching.

I don't think you wrote that otherwise you wouldn't be asking for the errors you encountered.

The code you posted compiled just fine on my old BCC compiler. I just had to remove the welcome_screen function which wasn't defined anywhere. It's a console application with a dull but acceptable GUI. This is definitely a very old application you got form a book or internet.

cprintf and textcolor functions are really old ones, I remember using them. You should instead use the SetConsoleTextAttribute function, google it and you'll find what it does. It should work with cout but if it doesn't you'll have to use WriteConsole function.

No function works exactly like the beautiful getch, but you'll have to find other ways. getchar is one. I suggest you go through the msdn website because it's the best place to start.
