How to sort array and eliminate duplicate array?

[mingke]

Hi...

I'm having some difficulties to sort two different array (say X and Y), these arrays state the coordinate in x and y axis..so, if X change, Y has to change.

I have unsorted array and I want to eliminate array with the same value...

Here's my code which doesn't work:

 
#include <stdlib.h>
#include <math.h>
#include <stdio.h>
#include <conio.h>


int main ()
{
     float X[4][4][24],Y[4][4][24],P[4][4][24],Q[4][4][24],R[4][4][24],S[4][4][24];
      int i,j,k,l,m,n,a,b,c,d;


X[0][0][0]=-1.414214;	Y[0][0][0]=0.000000;

         }
        }
     }


getch ();
}

I don't know why, but there are some arrays which are not eliminated even though the value are same.

Could you help me please?

Thank you
