I have been trying to compile a code using the information hiding method but am unsuccessful. I am using the BORLAND Compiler Version 5.02.
The Code that I am trying to compile could be found here:

http://web.cs.gc.cuny.edu/~armanartuc/4100/notes11.html
It is the professor code, so i don't think the problem is with the code.

I have copy and pasted this file and have given them propriate names, and placed them all in a single folder in C drive called program.
Then loaded the TEST.CPP file in BORLAND and pressed the compile button, but it didnot work.

Can anyone tell me what am i doing wrong?
regards

1 - Cut and paste the exact code you're trying to compile into your post (use [code] tags)
2 - Post the errors you're getting

Hopefully then, someone will be able to help you.

I'm going to take a look at your code, but you tell your professor I said he/she is full of shit. One who is teaching the language should know that 'main' returns an int and write it accordingly. SHEEEEEEEEEEEEEEEEEEEEEEEEEESH, blow my nose in my jockeys and call me a sticky bun!!!!!!!!!!!!!!!!!

EDIT: the program compiles and runs, using VC++ 2005, and produces the following output:

Quote:

0th element of the list is6
1th element of the list is5
2th element of the list is9
0th element of the list is5
1th element of the list is9

I'll try it with Borland 6 and let you know.

Seif · Apr 26th, 2006, 7:24 PM

his is void main so it doesn't return an int DaWei

j/k man, my lecturer got most of my class into the same filthy habit

DaWei · Apr 26th, 2006, 7:34 PM

Shit fire, Seif, I realize that it's declared 'void'. That's what the hell I said. "'main' returns an int" implies more than a return statement, it implies a proper definition. That form shown is incorrect, despite the fact that some compilers tolerate it.

At any rate, this is the output produced when compiled with Borland 6.

Quote:

0th element of the list is6
1th element of the list is5
2th element of the list is9
0th element of the list is5
1th element of the list is9

You need to set up your environment correctly, if anyone in charge there knows what the hell they're doing.

I have visual C++ too ... but i dont' know how to compile in it.
In BORLAND there is only one button,.. just press it and the code compiles.

Mack1982 · Apr 26th, 2006, 7:38 PM

One more question,.
If one has a working program not written in this format i-e all the code is in a single file. One can easily break it into the above kind of files, right?

Time to quit relying on yo' mama and yo' prof and learn a few simple things on your own. In answer to your last question, 'yes'. One doesn't have to break it up, even. It's an organizational thangy that you'll understand the first time you have an application containing multiple thousands of lines of code written by a team of programmer's using a handful of third-party libraries.
