表 4-10 投影檔內容 投影片內容 Lecture Selection : Switch Statements

Last time , we talked about how we can use the various forms of the if statement to make decisions in our programs

This time , we'll look at how we can use another statement - - the switch statement

- - to make decisions

Another statement we'll use to perform selection in our C# code is the A : else statement

B : switch statement C : witch statement D : warlock statement

Start IDE and open Console App project

Read in a your n from the user and print a message if they say y ( using a switch statement )

Add clause for a n message Add default clause

Recap We discussed how to use the switch statement to select what our program does

Next Time We'll discuss various applications of the selection construct in our games 線上摘要器 Auto Summarizer 能還原英文大小寫，Free Summarizer、

In this lecture , we're continuing our discussion of the selection control structure .

This time , we're going to look at another C# statement we can use to implement the selection control structure in C# .

And the way the switch statement works is we type the word switch , which is a keyword .

Other programming languages let you do that .

So it turns out , that we can list multiple cases , multiple values for the answer variable in this particular case that will do this stuff here .

Still showing you that y works in both cases .

Where it figures out which of these things matches , if you will , and does the appropriate stuff inside .

An enumeration is basically a data type that has specific values . We'll look at enumerations and see how they all work so ,

This time , we're going to look at another C# statement we can use to implement the selection control structure in C# .

So it turns out , that we can list multiple cases , multiple values for the answer variable in this particular case that will do this stuff here .

And so , if I just stack these values like this , then I can check both answer being lower case y and the answer being upper case y .

I'll point out that I cannot down here decide , oh I want to do another thing with lower case y , because that has already been included .

And , we're still going to have to add a break , because we add a break at the end of every clause we include in a switch statement .

That statement is called the switch statement .

That error message says we can't fall through from this case to other cases . So it turns out , that we can list multiple cases , multiple values for the answer variable in this particular case that will do this stuff here .

And so , if I just stack these values like this , then I can check both answer being lower case y and the answer being upper case y .

Because we sure don't want to have to say , case a , case , upper case A , case b , all of the other possible characters that are not y or n .

So the new statement we're looking at is the switch statement .

And the way the switch statement works is we type the word switch , which is a keyword .

So we have case , lower case y .

And that error message says we can't fall through from this case to other cases . So it turns out , that we can list multiple cases , multiple values for the answer variable in this particular case that will do this stuff here .

And so , if I just stack these values like this , then I can check both answer being lower case y and the answer being upper case y .

Because we sure don't want to have to say , case a , case , upper case A , case b , all of the other possible characters that are not y or n .

I'm going to have you , if you do the optional lab , I'm going to have you do some practice with both if statements and switch statements , because they're both useful tools for selection .

So , you might wonder why we care ? If we already have this if else , if else structure , why would we want a switch statement instead ? And it turns out that I covered it here because it's sort of the other statement we use for selection in C# .

And , we're still going to have to add a break , because we add a break at the end of every clause we include in a switch statement .

Because we sure don't want to have to say , case a , case , upper case A , case 與 Free Summarizer 摘要器只有直接提到關鍵工具名稱，並未提到此章節想 表達的意義，較無法直接聯想到投影檔的涵義。而 Tools4noobs 因並未將生 成摘要依照原始文字稿句子順序重新排序，會造成前後文內容毫無頭緒的
