How to check for duplicates in an array

[brute34]

Hey guys I am currently taking a class for c++ and one of problems I for an assignment is that I have to take 7 values from the user but they cannot be duplicates. I am having trouble writing the code so that when a duplicate is found it alerts the user and they have to enter another number. This is the function that I have so far. Any help would be appreciated!

 void getLottoPicks(int picks[], int size)
{
	cout << "Please enter your 7 lotto number picks between 1 and 40." << endl;
	
        for(int count = 0; count < size; count ++)
	{
		cin>>picks[count];
        }
}

The difference in your case is that the candidate number is one that is accepted from user input (instead of one that is randomly generated).
