Simple Program to remove Duplicate Element in an Array

PROGRAM:

#include <stdio.h>

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;

}
