Determining whether the set is reflexive, symmetric, anti symmetric and transtitive

[zing14]

I am having trouble finding out how to code this. I understand what each one is and know how to tell by looking but cannot figure out how to create functions to check whether it is either reflexive, symmetric, anti-symmetric, and/or transitive (it can be more than one). Here is the exact problem. Given a set of binary relations, determine whether the set is reflexive, symmetric, anti symmetric and/or transitive. Here are the sets:

0 1 2 3
0 0
1 1
2 2
3 3

x y z
x y
y z
y y
z z

x y z
x x
y z
x y
z y
x z
y y
z x
y x
z z

1 2 3 4 5 6 7 8
1 4
1 7
2 5
2 8
3 6
4 7
5 8
6 6
1 1
2 2

What compiler are you using?

You two should help each other.

Here is what I have come up with but my functions are not working properly because I am getting false for the first set being reflexive when it should be coming back true. Also, I can't even get my transitive started.. Any help??

#include <iostream>

using namespace std;

void reflexive(int a[], int sizeOfA, int b[], int sizeOfB)
{
	int i, j;
	bool test;
	bool hold = true;

	for(i = 0; i < sizeOfA; i++)
	{
		if(hold == true)
		{
			for(j = 0; j < sizeOfB;)
			{
				if(b[j] == a[i])
				{
					hold = true;
					break;
				}
				else
				{
					hold = false;
					cout << "Reflexive - No" << endl;
					break;
				}
			}
		}
	}
	if(hold == true)
	{
		test = true;
		cout << "Reflextive - Yes" << endl;
	}
}
