Challenge: Array Declaration

Create an empty array called heights of type float and length (size) of 7.

main


              12345678910111213
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			// Declare an array below this line
            ___
        }
    }
}

The syntax of declaring an empty array is datatype[] arrayName = new datatype[size];.

main


              12345678910111213
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Declare an array below this line
            float[] heights = new float[7];
        }
    }
}
