Discrete math and programming

[ironeagle]

I need advice on how to approach the following problem. Can I use C++ to write a program that classifies functions? Using relations from two sets to determine whether they are functions, compositions etc.

Are there resources I can use to begin this program; since I am a novice programmer?

Hi. I don't think there are many limits on what you can design with C++. There is code out there that may be of assistance to you and the learning curve will be brutal. check this out...

Thank you, but I am still in the dark. I dont even know how to input relations from sets and test for functions. I dont wish to sound inept but infact I am. I intend to search some C++ books but hoped to find a starting point online.

Can I suggest you present a simple mathematical problem involving relations and sets with specifics and then start with basic questions of how to program it. Start small and it will build over time.

Write a program to classify functions.Input two relations R1,R2 both from a set A to a set B, as ordered pairs (a,b). The sets must be specified. Test whether the relations are functions.

#include <Set.h>
Set<int> A,B;

I have no other resource of code to use to declare these relations etc.
Does this make sense?

Test whether the relations are functions.

This sounds like maths speak, but I do not know what it means.

We can help you with the programming skills but you are going to have to describe your problem so we can understand it.

Do not feel constrained to write in C/C++ which you are not terribly familiar with yet, explain your problem in the language you find easiest making it clear what operations need doing.

For instance how do you test if a relation is a function?

IIRC a relation is a function if it passes a vertical line test. Or is it horizontal? I can never remember. You will probably find better help if you were to find a mathmatics forum. Most of the experts on thescirpts have forgotten all their math knowledge over time since none of us really use it.
