Helping Noname one more time (again) was starting to wear on me. As was beginning to happen too often, the minute I thought I was free to get a little rest, someone else had other plans. Sara cornered me just as I was opening the door to my room.

"Hi, Teo! I heard that you were chosen for the 

 project. Congratulations!" Sara said. 
"Thanks, Sara," I said, " but can we talk another time? I need to rest..." 
"Oh, sure," she said sarcastically, "I didn't realize you wanted to fail your exam. What do you think is more important: sleep, or passing the exam and getting a ticket to 

Of course, another set of tasks or lessons to be had. Endless work around the base. To be honest, all I was looking forward to was Noname sending me back to my normal life. But I knew how to play my role, and I replied "I hope this thing you want to tell me is really that important." I answered.

"It is. In short: we fed a code analyzer all the code that you have written so far, and it determined that you have never used a

"Of course I've never used a 

 , I don't even know what it is!" 
"You'd better learn it! At the exam, Infinity can (and often does) ask about it!" 
"Ok, let me just take some coffee. Then I learn about switch statements, and everyone leaves me alone so I can get some sleep."

"Let's start with a simple program where the user inputs questions to the console," Sara started. "The program should do the following:

Answer with "I love you!" when the user asks "Do you love me?"

Answer with "You look awesome!" when the user asks "How do I look today?"

Answer "I have no clue what you are talking about." when the user prints something else.

Can you write this program for me?" 
Despite my distinct lack of sleep, I managed to write it in one minute flat.

 statement is used when you have two logical choices and your program needs to choose between them. In this case, you have three logical choices, and because of that, you had to use 

 several times. You can probably guess where this is going - this is why the 

statement is used to perform different actions based on different conditions.

Here's what your code looks like when we use the 

"I guess this was important enough to keep me out of bed a bit longer!" I said. "Why hasn't anyone told me about switch statements before now?" I asked. 
"To be honest, Teo, we purposely wanted you to NOT learn the most powerful aspects of C# because we didn't trust you. But then you started learning things outside the base, like the 

 statement from that guy from the C gang, and we didn't have much of a choice." 
"Thanks, I suppose," I said. 
"Now back to the

 values. If there's a match, the associated block of code is executed. If there is no match, the

"Okay," I replied, "That seems easy enough. What does

"Good work!" Sara said. 
"Yeah, this isn't that hard, actually," I answered.

"Ok then, let's go to something a bit harder. First of all, there can be more than one line of code in every 

 block. Second, the type of variable that you check in a 

At that point, I was really exhausted. Sara looked happy because I had managed to solve all but one of her tasks for the 

 statement, and I was happy because there was only one last to go and I could
