when i run turbo C 3 computer slows down..
processor usage is always 100 % when its running..
same in college where they hv pentium 4 and 521 MB RAM
what to do now !! which editor to use !

well i can't compile most of my programs in dev C++ its out.. !

example like far is not allowed in there..!

Well, Turbo C++ is a 16bit DOS Application created in 1992.

32bit Windows (especially NT based ones) Emulate it. (similarly 32bit Apps are emulated on 64bit OS like WinXP x64.. 16bit Apps wont even work there!)

Two Methods:
1. Use it with DOSBox
2. Use Borland C++ Compiler Tools and Relo Editor.
Zeeshan had posted a Turorial here I suppose.

try to open it thru DOS prompt.

ex. suppose u have tcc folder in C drive,
then go to command prompt and type...

cd\
cd tcc
tc

Now, I think it will NOT take that much memory !

Both work the same way :)

NT based Windows don't have true DOS Prompt. (Only DOS based 16bit/32bit Windows like Win95-WinME have them)

its slows down only when u minimize it/task switching.... and come back to it.... a lame reply but a fact :p

just dont switch programs when using turbo c

I think it may be due to some virus.The same happened to me when I installed turbo c and it was using up all system memory.
Now I am happy with Dev c++(in windows)
And Linux(best way to program).

^^lol but it happened to me My turbo c was actually infected my a virus(according to Nod32).

And I suggest we should stop using turbo c now as it is not upto ISO standards.

Your solution:

It happens in NT based systems. Use this for running TC3 or other DOS based applications where such problems occur:

If the memory usage comes 100% when you run Turbo C++ , or when you run any other applications. If it is so then look for Spywares or Adwares.
If not then reinstall the C++.
delete the folder and backup your progrms and reinstall the c++ and scan the installed folder with a good updated antivirus.

this happened with me once in my college, the Compiler was taking about 15sec to compile a program with just one line:D

i did complain to my teacher, She said chal toh raha na, bus wait karo
:lol::lol::lol:
however at home it never happens with me as i use award winning GCC complier;)

its not a problem with turbo c++ only
turbo prolog and turbo assembler also make usage go to 100%

only thing to do is be patient

If its the cas eof your gui apps slowing down, i can help with what i used to do...
1. open task manager and locate ntvdm.exe
2. right click on it and select Set Priority -> BelowNormal.
You're done.
If its your programming/ compiling which is slow, i'm of not much help here.

emulation comes with costs.

On dual core or HT enabled it takes up 50% CPU usage.

Dude use dev c++ its waaay better than turbo sh!t or better still if you really wanna learn programming then start using linux.

^^ Agreed.... We have to submit a project in C++ and all PCs in my college run TurboC... and that cannot even recognize namespaces.

I asked for a Linux box and think I will get one on the day of presentation. :)
