int a[20], i, j, k, n; clrscr();
printf("\nEnter array size: "); scanf("%d", &n); printf("\nEnter %d array element: ", n); for(i = 0; i < n; i++)
{
scanf("%d", &a[i]);
}
printf("\nOriginal array is: "); for(i = 0; i < n; i++)
{
printf(" %d", a[i]);
}
printf("\nNew array is: "); for(i = 0; i < n; i++)
{
for(j = i+1; j < n; )
{
if(a[j] == a[i])
{
for(k = j; k < n; k++)
{
a[k] = a[k+1];
}
n--;
}
else
{
j++
}
}
}
for(i = 0; i < n; i++) { printf("%d ", a[i]);
}
getch();
}

output
Enter array size: 5 Enter 5 array element: 11 13 11 12 13 Original array is: 11 13 11 12 13 New array is: 11 13 12
