Plotting graph in turbo c++ 2.01,linux

I use the turboc++ 2.01 compiler to compile to compile my C programs,and i have installed it in ubuntu linux using dosbox.Now, my prof. has asked me to draw the graph of a data inputted by the user WITHOUT USING ARRAYS.
So, i have written a for loop which will get the x coorinate and y coordinate data.Now, i want to know how to plot a graph of this?Do i have to use any library in turbo c or do i have to call any external program?If i need to do either of these, then how?please help me as i am a beginner at these.

No one except Adak will help you. Since all of us left this dead compiler already.
Why not use gcc in linux?! This is the craziest.. using turbo c in linux using dosbox!

I don't know of anything special to use for this. If the prof hasn't given you any hint of what he wants, then I'd try to take the given value, and first, find it's x value within the range of the graph - corresponding to the row on the screen. Then repeat for the y value, which would correspond to the column on the screen.

It's easier to use an array because you are referring to one object element at a time, yet it holds all the other array values, as well. Still, it can be done "on the fly".

I use Turbo C/C++ 1.01, so your options may be different than mine.

well....i used i am learning c in tc++....moreover,i used gcc and got pained with it...it wont accept if you print a float with %d--i.e., it doent accept float to in conversions, it doesnt accept conversions from char to int,moreover, some commands like clrscr(); do not work.

also, suppose i want to use tc++ in windows, then?

well,i earlier used tc 1.01, its similar

actually what the professor wants is that the user must be able to input the coordinates of five points, both the coordinates of each point at every loop instance.I have done it.Now, the main part is plotting the graph.Plz help me!!!!!!!!!!!!

Gcc give you warning while your turbo crap cannot. Because variadic function like printf cannot promote its arguments. clrscr is non standard C function. You have to use like curses library.
I discouraged using tc. Because many tc programmers think their non standard wrong code works with tc means they are right.

but when u compile some program that uses math.h header file , u need to write a long command in the terminal in order to compile it.Is there any better alternative to that in gcc?
Moreover, even if i use gcc, how do you "call" something like gnuplot?????

Use an IDE.

Code::Blocks

Click on the red text ... Multiple linux versions available.

thanks for suggesting a good compiler but will gnuplot work with code::blocks?If yes, then how do we call it ina c program?I could not understand the gnuplot tutorial as it is a bit screwed up

Code::Blocks is not a compiler. It's an IDE.

Use it with GCC and it will compile anything GCC (more or less the standard compiler for *nix systems.) will compile.
