class Arrays {
   static void Main() {
      int[] primes;
      primes = new int[10];
      primes[0] = 2;
      primes[2] = 5;
      System.Console.WriteLine("The 3rd prime number is: {0}",
         primes[2]);
      double[] temperatures = new double[3];
      temperatures[0] = 70.0;
      temperatures[1] = 75.0;
      temperatures[2] = 73.5;
      System.Console.WriteLine("Forecast for tomorrow's high"
         + " temperature: {0}", temperatures[2]);
   }
}

Output:

The 3rd prime number is: 5
Forecast for tomorrow's high temperature: 73.5
