Getting the length of a string

Add a new console application project named Ch04_ManipulatingText. Set the solution's startup project to be the current selection.

Sometimes, you need to find out the length of a piece of text stored in a string variable. Modify the code to look like this:

using static System.Console;

namespace Ch04_ManipulatingText
{
    class Program
    {
        static void Main(string[] args)
        {
            string city = "London";
 WriteLine($"{city} is {city.Length} ...
