This lab depends on the introductory material in earlier in this chapter, particularly keep handy Summary of String Length and Some Instance Methods. Be mindful of the processes developed in class filling in A Creative Problem Solution.
Design, compile and run a C# program to accomplish each of the following tasks. Add one part at a time and test before trying the next one. The program can just include a Main method, or it is neater to split things into separate methods (all static void, with names like ShowLength, SentenceType, LastFirst1, LastFirst), and have Main call all the ones you have written so far (or for testing purposes, just the one you are working on, with the other function calls commented out). All input from the user should be preceded by a meaningful prompt.
Read a string from the keyboard and print the length of the string, with a label.
Read a sentence (string) from a line of input, and print whether it represents a declarative sentence (i.e. ending in a period), interrogatory sentence (ending in a question mark), or an exclamation (ending in exclamation point) or is not a sentence (anything else).
This may be the first time you write a conditional statement. It makes sense to only make small changes at once and build up to final code. First you might just code it to check if a sentence is declarative or not. Then remember you can test further cases with else if (...).
Read a name from a line of input. Assume first and last names are separated by a space. Print last name first followed by a comma and a space, followed by the first name. For example, if the input is "Marcel Proust", the output is "Proust, Marcel".
Improve the previous part, so it also allows a single name without spaces, like “Socrates”, and prints the original without change. If there are two parts of the name, it should work as in the original version.
Run the program (with parts 1, 2 and 4 active) from a terminal window and show your TA when you are done. You should run it twice to show off both paths through part 4. Alternately have the main program just call part 4 twice.
