How to check if an element exists in an array or not? (C++)

Question

What i wanna do is>>
Given n = 5
Given input --> 2 3 2 2 3

array [n]
Cin > input
Check(if element in array)
If not, then store the value in array..

Else..continue

For example: first input> 2..and the array is empty..so 2 not in array..then store it in array..

// Only store unique values..

I am having problem at the if statement..how can i check the value already exists or not?
