I'm new to C# we have an activity to create a lottery game.

1 matching number won $10 2 matching number won $100 3 matching number not in order $1,000 3 matching number in order won $10,000

class Program
{
    static void Main(string[] args)
    {
        // Matching numbers awards
        int rNumMatchOne = 10;
        int rNumMatchTwo = 100;
        int rNumMatchThree = 1000;
        int rNumMatchFour = 10000;
        // Generate random numbers
        Random randomNum = new Random();
        // Integers Declaration
        int rNum1;
        int rNum2;
        int rNum3;
        int rNumIput;
        int guessNum;
        // Arrays Declartion
        int[] guessNumMatch = new int[3];
