Try this: using System; class Program { static Random rand = new Random(); static void Main() { int[] numbers = new int[1000]; for(int i = 0; i for(int i = 220; i for(int i = 340; i for(int i = 640; i for(int i = 900; i Shuffle(numbers); int[] counts = new int[5]; Console.WriteLine(The random numbers are
); foreach(int number in numbers) { Console.Write( {0} number); counts[number-1]++; } Console.WriteLine(
The totals are
); for(int i = 0; i Console.ReadKey(); } static void Shuffle(int[] numbers) { int len = numbers.Length; for (int i = 0; i { int r = rand.Next(i len); int temp = numbers[i]; numbers[i] = numbers[r]; numbers[r] = temp; } } }
