At this point, for time reasons, I have to leave the programming part of my dissertation for a few week.
I therefore wanted to take this opportunity to thank you for your help and patience. I have...

Alright, that is very good to know, I thought the variables were only to be called in that way when you desired to modify their value within the function.
The function now runs, and the Linear...

I ran a cin >> through the text and found that the error is in the
glp_load_matrix(lp, OBJ.n_rows*3, &ia(1), &ja(1), &ar(1)); statement... any ideas?

It may possibly be that I use too much memory?

I feel the code should make more sense now, but the "The program '[16172] top.exe: Native' has exited with code 3 (0x3)." error still appears... Here is the code now if you feel like having a look.

Thank you!
This is all very useful, and the std::Vector (or rather arma::Col) that I am now using thanks to you works great!
I actually tried to do it this way earlier, but did not add the [0]...

The error only occurs when I call the linprog1 function, so the error should lie in the second code.

#include <cmath>;
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string>
#include <iomanip>

Sorry, that is suppose to be char* and char, not double* and double

I got the code to work! Thank you for all your help! :)
By the way, I created a 1d array using the trick double* x = new double[var]; which seems to be the only way of creating an array with a...

I made it past that problem by adding files to the resources folder. I now run the program fine, but when the cmd prompt appears it appears with a message claiming that the dll file used is missing...

Ah once again I moved on, I simply took all the files in the folder, such as dlls and libs and put them under resources, now the error that appears is that the file "glpk_4_47.dll is missing" so I...

Clearly if anyone wants to have a look at the package to see if they can make it work, that would be much appreciated.
The file can be downloaded for free from https://www.gnu.org/software/glpk/

Modified the text! :) I think you are right about the dependencies, but I am not sure how to make this work.. All the linker --> input --> additional dependencies allows me to do is write names of...

Cheers Paul :)
You are right about the fact that I do not know enough about c++ yet, as I keep getting into trouble... I have now moved onto trying to add the gnu glpk library to my code, but I...

I am new to c++, so I apologize for the possibly poorly formulated question below.
I am trying to use gnu glpk library, and I am doing something wrong.
I code in visual studio 2010. To use the...

Thank you Paul!
I needed to rethink what I was doing and am now on the right track! It is annoying however that now I have stumbled upon:

Thank you for your reply Paul.
Although I am new to C++ I understand the concept of prototyping. I apologize for the confusing formulation of my question. I believe this function I am trying to use...
