Finding Unique Element in an Array

Problem Statement
Write a function findunique () which takes an arra A, its size n and another array B as parameters.The function stores in B the unique elements of A. It returns the size of B.
#include<stdio.h>
int findunique(int a[],int b[], int i); int main() { int a[50],b[50],i,d,j,y; printf("enter the numbers respectively enter ctrl-d in the end \n"); i=0; while(scanf("%d",&d)!=EOF) { a[i]=d; i=i+1; } y=findunique(a,b,i); printf("%d elements are unique among %d \n",y,i); for(j=0;j<y;j++) { printf("%d ",b[j]); } printf("\n"); return 0; } int findunique(int a[],int b[], int i ) { int count,j,temp,k,counter; count=0; for(j=0;j<i;j++) { k=j+1; counter=0; while(k<i) { if(a[j]==a[k]) { counter++; temp=a[j+counter]; a[j+counter]=a[k]; a[k]=temp; } k++; } if(counter==0) { b[count]=a[j]; count++; } j=j+counter; } return count; }
