Find the duplicate numbers in an array

Thank you very much! I got stuck on starting the for loop int i = 0 which made an error for me. This helped a lot :).

Thank you very much for this video. It helped me with my programming assignment.

The above program will work as expected only when the numbers are only repeated 2 times else it will give output more than 1 time. Suppose 3 is repeated by 4 times in array then output will be .
O/P :-
Duplicate number is: 3
Duplicate number is: 3
Duplicate number is: 3
so it is redundant to show same msg more than once.

What if we want to determine the number of duplicates? How do we write that code? Please give me an answer!
