How do I store my numbers into an array?

In my code, I am trying to generate 5 numbers. If any of the numbers equal to 4, then I want to store that 4 into an array. Currently I'm having trouble and my code will not store the 4 into the array.

static void Main()
    {
        Random rand = new Random();
        int total = 0, randInt;

        Console.WriteLine("The computer is now rolling their dice...");
        int[] fours = new int[total];

        for (int i = 0; i < 5; i++)
        {
            randInt = rand.Next(10);
            Console.WriteLine("The computer rolls a {0:F0}", randInt);
            if (randInt == 4)
            {
                total +=fours[i]; //Here I am trying to store the 4 into the array of 'fours'.

            }

        }

        Console.WriteLine(total); //This currently prints to 0, regardless of any 4's the random number generator has generated. I want this to print out how many 4's I have rolled.
        Console.ReadLine();
    }

This:

total +=fours[i]

Will attempt to increment total with the int found at index i of your array (which will currently be 0, because int defaults to 0).

This:

fours[i] = 4;

Is how you assign 4 to the ith index in your array.

Read about how the assignment operator works in C#

The = operator is called the simple assignment operator. It assigns the value of the right operand to the variable, property, or indexer element given by the left operand.
