Problem Set 1

Your First C# Program(s)

Due 11:59pm Monday Sept 18

Note: you should use Visual Studio .NET for this assignment and all others in this course.

Do program design exercise 18 in Chapter 2 of the text.

Solution.

Do program design exercise 19 in Chapter 2 of the text. You should print your result nicely, for example something like:

"52,400 seconds is the same as 14 hours, 33 minutes, and 20 seconds."

Solution.

A "mad-lib" is a sentence with certain words left out. You ask people who don't know what the sentence is to give you words of particular parts of speech; these words are then inserted into the sentence to provide weird results. For example:
```
"The ______ professor ______ my ______, and I've never recovered."  
```
This mad-lib needs an adjective, a verb (past tense), and a noun, in that order, in the three blanks. When the blanks are filled in, it might produce the following sentence:
```
"The wise professor graded my paper, and I've never recovered." 
```
or
```
"The purple professor ate my computer, and I've never recovered."
```
Using this mad-lib idea, write a program that asks the user to input three words (an adjective, a verb, and a noun) and then prints the completed sentence. Run your program several times (without recompiling), providing different words. A sample output of the program might look like this:
```
Welcome to the Game of Mad-lib!
Please input an adjective: wise
Now input a verb (past tense): graded
Finally, input a noun: paper

*** The wise professor graded my paper, and I've never recovered. ***  
```
Note that, for clarity, the user input is underlined.

Solution.

Rewrite your solution to (3) in the following way: Define a method "Query" that takes a string parameter, and returns a string result. The string parameter is a query such as "Please input an adjective:" or "Finally, input a noun:", and the string result is the string that the user types in.
