Find Duplicate Elements in Array in C++

C++ Program to Find Duplicate Elements in Array

Array is the collection of similar data type, In this program we find duplicate elements from an array, Suppose array have 3, 5, 6, 11, 5 and 7 elements, in this array 5 appear two times so this is our duplicate elements.

#include<iostream.h>
#include<conio.h>

 void main()
 {
  int i,arr[20],j,no;
  clrscr();
  cout<<"Enter Size of array: ";
  cin>>no;
  cout<<"Enter any "<<no<<" num in array: ";
  for(i=0;i<no;i++)
  {
   cin>>arr[i];
  }
  cout<<"Dublicate Values are: ";
  for(i=0; i<no; i++)
   {
    for(j=i+1;j<no;j++)
    {
    if(arr[i]==arr[j])
    {
    cout<<"\n"<<arr[i];
    }
   }
   }
  getch();
 }

Enter Size of Array : 5
Enter any 5 elements in Array: 
5 4 5 2 3 
Duplicate Elements are: 
5
