Code:
#include
int main()
{
int array[50];
int *ptr;
int i, j, k, size, n;
printf("\n Enter size of the array: ");
scanf("%d", &n);
printf("\n Enter %d elements of an array: ", n);
for (i = 0; i < n; i++)
scanf("%d", &array[i]);
size = n;
ptr = array;
for (i = 0; i < size; i++)
{
for (j = 0; j < size; j++)
{
if (i == j)
{
continue;
}
else if (*(ptr + i) == *(ptr + j))
{
k = j;
size--;
while (k < size)
{
*(ptr + k) = *(ptr + k + 1);
k++;
}
j = 0;
}
}
}
printf("\n The array after removing duplicates is: ");
for (i = 0; i < size; i++)
{
printf(" %d", array[i]);
}
return 0;
}
Output:
Enter size of the array: 6
Enter 6 elements of an array: 12
10
4
10
12
56
The array after removing duplicates is: 12 10 4 56
