Car racing in turbo C

Welcome to the 21st century guys...turbo c++ in that sense, is something from the last century which didn't bother to make it to this century (read, didn't bother to update itself). But C++, in all glory has been standardized, i guess, in the last century itself. But Mr. Turbo doesn't even know that!!!

Your code now is indented, but that's not the only "art" in programming. Your code has no single comment.

Here's an open challenge:
can anyone explain the code?? I bet even you (who claims to have written it once upon a time) can't explain.

Here's an open challenge:
can anyone explain the code?? I bet even you (who claims to have written it once upon a time) can't explain.

Now I'm to busy...
I will explain it on next month on next month. Though could you tell me about problem on the style and code of programme..

>Now i'm too busy...

relax and take some time out to figure out the problem in your code pertaining to "code style".

Read good books and also read about programming style. (just google it up)

And always remember:
"Programming is more about the art of programming"

I may not be the most experienced coder out here, but Ancient Dragon surely is. So if he has labeled your code as "messy" you better take it seriously, unless off course you plan not to code for the industry.

Though could you tell me about problem on the style and code of programme..

I hope you do happen to know that BGI Graphics are deprecated and obsolete. 16-bit DOS compilers shouldn't even be allowed to compile. Don't get it why schools still teach this stuff.

Don't get it why schools still teach this stuff.

Probably because it allows students to use the included <graphics.h> file without having to add or link any further libraries so they can easily make graphic style programs such as the one above.

Of course, any seasoned programmer, would laugh at turbo c++ because it doesn't follow the standard. In fact you're probably safer writing the code entirely in c.

Schools go with the train of thought that kiddos just need to learn programming basics such as for and while loops with simplistic functions. The semantics as to why it is bad as c++ is generally ignored.

BGI Graphics are not supported under windows...

BGI Graphics are not supported under windows...

Since when? Last time I compiled code I wrote 20 years ago, it compiled and worked. And this was within the last year.

Even though BGI and Turbo are old, if you have something to complain about it would be much more helpful if you check your facts first. And keep opinions to yourself. They are not helpful when there's nothing the OP can do about it.

Turbo c is outdated,but still in our college they use it even to do complex programs

I can't even get Turbo C to install on 64-bit Windows 7, let alone try to compile anything with it. There will come a day when India's universities will be forced to upgrade their school's compilers and teaching. They are putting their students at a huge disadvantage by teaching with such old tools.

Exactly....
Most probably they may upgrade to Visual C++ or
Dev C++ which is free.

My guess is Dev C++, since it's no longer an active project :icon_wink:

I don't understand why the condition in India is so pathetic...!! The whole higher education system in India sucks when it comes to Information Technology and Computer Science...my Indian friends...what say?? Shall we start a revolution??

like wat revolution u want to start

like all students protesting the use of antique softwares may be??

On a serious note...its all about spreading awareness. I have seen many students are simply ignorant about the gotchas of using turbo c or about the cons of writing non-standard code. So on your part you can simply spread the awareness amongst your friends and they in their turn will spread it to others and we can just hope that one day things will change. But for that we really need to appreciate the change. People are too relaxed and it seems that they don't want the change. This attitude needs to change. And change fast.

Lol, tried that. Got labelled as an arrogant freak from people who don't even care about programming! The lame-boy excuse is "It works, doesn't it". If only one day they'd wake up to their PC being toasted by a app they created, just because it returned a value of -5266E-12 to Windows, I'd be a happy man! :)

no use of doing that
In our college they just teach us commad line programs they will never come across GUI programming.even though we change to any other IDE they just do command line programs

Let's not get too far of-topic. If you want to discuss the educational system in India be my guest, but please do it in the Geek's lounge.

Here is another Turbo-C car racing game ..
