Thread: Removing Duplicates from an Array

Hi, I have a homework assignment for my programming course that I'm having a lot of trouble with. The object is to take an array, and remove all of the duplicate numbers, and create another array without the dupes. Here's my code right now:

Code:

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include "simpio.h"
#define size 10

int removedup(int inpArray[],int arraySize, int outArray[]);

main()
{
	int inpArray[size],outArray[size],i;
	printf("Enter integer values for the array");
	for(i=0;i<size;i++)
		inpArray[i]=GetInteger();
	i=removedup(inpArray,10,outArray);
	printf("%d\n",i);
	for(i=0;i<size;i++)
		printf("%d\t",inpArray[i]);
	for(i=0;i<size;i++)
		printf("%d\t",outArray[i]);
}

int removedup(int inpArray[],int arraySize, int outArray[])
{
	int i,temp,j,k;
	k=0;
	for (i=0;i<size;i++)
	{
		
		temp=inpArray[i];
		for (j=0;j<size;j++)
		{
			if (outArray[j]==inpArray[i]) 
			{
				b	break;
			}
			else outArray[k]=inpArray[i];
			k++;
		}
		
	}
	return k;
}

The function removedup is supposed to return the size that the second array (The one without duplicates) should be, but when I run it, I always get an output of either 10, or the program terminates after the 9th cycle of i. Thanks in advance for any help.

Thanks for the help, but there seems to be something wrong with my actual function to check for duplicates. Here's what I'm using, please tell me if you see the flaw, and thanks again.

Code:

int removedup(int inpArray[],int arraySize, int outArray[])
{
	int i,newSize,j,temp;
	for (i=0;i<size;i++)
	{
		outArray[i]=0;
	}
	newSize=0;
	for (i=0;i<size;i++)
	{
		temp=inpArray[i];
		for(j=0;j<=i;j++)
		{
			if (inpArray[i]==outArray[j]) break;
			else
			{
				outArray[newSize]=temp;
				newSize++;
			}
		}
	}
	return (newSize);
}
