    graph.h

    Dear All,
    Below is the fraction of a code (taken from Neural Networks for Identification, Prediction and Control by Pham and Liu) showing only the included header files. The authors advised to use MS QUICK-C (v1.0) but unavailability of it forced me to run the program using Dev-C++ and MS visual studio 2003. In both cases some errors appear due to graph.h. Can anybody suggest me some compiler instead of MS QUICK-C or any link for download it freely.

    Code:
    #include<conio.h>
    #include<graph.h>
    #include<stdlib.h>
    #include<float.h>
    #include<math.h>
    #include<stdio.h>
    
    ...
    ...

    That is really an ancient compiler.

    Is the code actually drawing graphics? Or is it just including that file "for good measure"?

    It is a code for implementing multilayer perceptron in Neural Network.Basically it will show results of three different functions(linear ,non linear,hybrid network) in a x(learning rate) and y(RMS error) plane based on some input value.

    Code:
    #include<conio.h>
    #include<graph.h>
    #include<stdlib.h>
    #include<float.h>
    #include<math.h>
    #include<stdio.h>
    
    #define n0 4           /*    input Layer     */

    Ok, so if you want that to work, you probably need to use graphics, and it may not be easy to convert. It probably isn't VERY hard if you have some experience with C and graphics programming.

    I don't think that particular compiler was very popular, so it may be hard to get a copy (at least in some sort of legal method).

    But having the header file won't actually help to get the code that is in the library file that is ALSO needed.

    I know that, but this might help him one step forward to his goal. I found this file, if its correct, so the other might be out there too.

    You can buy Quick-C versions here : http://www.emsps.com/oldtools/msquickc.htm#qc1dos

    You might try one of the legacy Borland Turbo C compilers. It is from that time period, I believe, and the dual C/C++ compilers (which can be set for either language), are good.

    They are available from Borland's legacy d/l site, google for the url.

    So does your interest in C begin and end with this single program?

    Or are you intending to use it for many other problems in future?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    I'm currently (for my own benefit) trying to port this to SDL.

    There are some typos in the code - did you actually type this in, or did you get it in electronic form from somewhere?
