Write a C++ program to find duplicate elements in the given array of n size, where n is entered by the user.

Write a C++ program to find duplicate elements in the given array of n size, where n is entered by the user.

Program Code:

#include<iostream>

using namespace std;

int main()

{

int i,j,n;

int array[20];

cout<<"Enter Size of array: ";

cin>>n;

cout<<endl;

cout<<"Enter elements into the array: ";

for(i=0;i<n;i++)

{

cin>>array[i];

}

cout<<endl;

cout<<"Duplicate values into the array are: ";

for(i=0; i<n; i++)

{

for(j=i+1;j<n;j++)

{

if(array[i]==array[j])

{

cout<<endl;

cout<<array[i];

}

}

}

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter Size of array: 8

Enter elements into the array: 1 3 5 2 4 5 2 1 

Duplicate Values into the array are: 

1

5

2
