Here's my solution (it work's ) but it became quite complex and due to the shifting the garbage value also shows.
Now will think on R.Stiltskin's idea.

Code:

#include <stdio.h>#include <stdlib.h>
#define MAXSIZE 10
int compact(int[]);
int main()
{
    int num=0, numarray[MAXSIZE]={0,0,0,0,0,0,0,0,0,0}, i=0;
    int top = -1;
    printf("Please enter some numbers. Enter -1 to stop.\n");
    while(num != -1)
    {
        scanf("%d", &num);
        if(top==(MAXSIZE-1) || num == -1)
        {
            printf("Done !\n");
            break;
        }
        else
        {
            top+=1;
            numarray[top] = num;
        }
    }


    while(i<MAXSIZE)
    {
        printf("%d ", numarray[i]);
        i++;
    }
    printf("\nPrinting compact numvers.\n");
    compact(numarray);
    getchar();
    return 0;
}
int compact(int changeArray[MAXSIZE])
{
    int i=0, j=0, k=0, l=0;
    while(l<MAXSIZE)
    {
        i=0, j=0;
        while(i < MAXSIZE)
        {
            if(changeArray[i]==changeArray[i+1])
            {
                j=i;
                while(j < MAXSIZE)
                {
                    changeArray[j]=changeArray[j+1];
                    j++;
                }
            }


                i++;
        }
        l++;
    }


     while(k<MAXSIZE)
     {
         printf("%d ", changeArray[k]);
         k++;
     }
     getchar();
     return 0;
}

I did not implement the size returning function as I am not very satisfied with the garbage values creeping in. Maybe I will modify to store 0/-1 instead of garbage and check conflict if user inputs the same.
