Thread: Array Comparison and Modification

This is what my code is intended to do: When called with the following array:

Code:

{ 1, 1, 1, 2, 2, 1, 2, 3, 3, 1, 1 }

, your function should modify the array to

Code:

{1, 2, 1, 2, 3, 1}

and store it.

Code:

#include <stdio.h>
#include <stdlib.h>
void compact (int[], int);
int main()
{
    int arrSeries[11] = {1, 1, 1, 2, 2, 1, 2, 3, 3, 1, 1 };
    int arrLength = 11;
    compact(arrSeries, arrLength);
    getchar();
    return 0;
}


void compact(int arrSeries[], int arrLength)
{
    int i, j= 0, counter=0, newArray[11];
    newArray[0]=arrSeries[0];
    for(i = 1; i != arrLength; i++)
    {
        if(newArray[j] != arrSeries[i-1]);
        {
            newArray[++j] = arrSeries[i];
        }


    }


    while(counter !=6)
    {
        printf("%d  ", newArray[counter]);
        counter++;
    }


}

However it is not working as intended. It works as if the IF statement doesn't even exist ! Where am I going wrong?
Thanks
