C# programming: how do I code this please

Problem 3 This problem requires a user to enter a series of strings. Each time the user enters a string, you must tell the user how long the string is. Then ask the user to enter another, longer string. Keep doing that until the user enters a string that is not longer than the previous string. Your output should look like the example below. The yellow highlights indicate user input. Example Output *** PROBLEM 3 *** Enter a string: Here's a string. That string is 16 character(s) long. Good. Now enter a longer string: Here's a longer string. That string is 23 character(s) long. Good. Now enter a longer string: Here's a MUCH longer string. That string is 28 character(s) long. Good. Now enter a longer string: This string is really super, duper long! That string is 40 character(s) long. Good. Now enter a longer string: Is this long enough? That string is 20 character(s) long. Sadly, that was not longer than the previous string
