C program to delete duplicate elements from an array. For example, if an array contains following five elements: 1, 6, 2, 1, 9; in this array '1' occurs two times. After deleting duplicate element we get the following array: 1, 6, 2, 9.
C program
int main()
{
int n, a[100], b[100], count = 0, c, d;
printf("Enter number of elements in array\n");
scanf("%d", &n);
printf("Enter %d integers\n", n);
for (c = 0; c < n; c++)
scanf("%d", &a[c]);
for (c = 0; c < n; c++)
{
for (d = 0; d < count; d++)
{
if(a[c] == b[d])
break;
}
if (d == count)
{
b[count] = a[c];
count++;
}
}
printf("Array obtained after removing duplicate elements:\n");
for (c = 0; c < count; c++)
printf("%d\n", b[c]);
return 0;
}
Output of program:
Enter number of elements in array
10
Enter 10 integers
1 5 1 2 3 9 2 5 8 6
Array obtained after removing duplicate elements:
1
5
2
3
9
8
6
