IN THIS CHAPTER, YOU WILL:

The result is, simply:

Logically, print "test" results in test being printed to the screen. However, the second line is the result of your code as an expression (more about these in 3). This is because almost everything in Ruby is an expression. However, print displays data to the screen rather than return any value as an expression, so you get nil. More about this in 3. Let s try something else:

winforms pdf 417 reader, winforms qr code reader, winforms upc-a reader, winforms data matrix reader, winforms ean 128 reader, winforms ean 13 reader, c# remove text from pdf, itextsharp replace text in pdf c#, winforms code 39 reader, itextsharp remove text from pdf c#,

SO FAR , this book has demonstrated how you can apply Beyond Bullet Points (BBP) in depth to a single presentation example. 4 showed you how Act I of the story template helps you choose the speci c ideas that you ll present to your audience s working memory in the rst ve slides of a presentation, and 5 showed you how Act II guides you through the process of setting the priority and sequence of the rest of the slides. 6 offered instructions on how to set up your storyboard and narration in Microsoft Of ce PowerPoint 2007, and 7 illustrated some of the many ways you can sketch your storyboard. Finally, everything came together in 8 as you set up custom layouts that align with the priority of your slides and you added the speci c graphics that are a good t for you, your headlines, and your audience.

This command seems logical on the surface. If 2 + 2 is equal to 4 and you re adding that to the end of "2+2 is equal to", you should get "2+2 is equal to 4", right Unfortunately, you get this error instead:

hole of great dimensions. If you execute a string where parts of the contents have been supplied by a user, you have little or no control over what code you are executing. This is especially dangerous in network applications, such as CGI scripts, which you will learn about in 15.

TypeError: can't convert Fixnum into String from (irb):45:in `+' from (irb):45 from :0

Review a range of presentation examples using the Beyond Bullet Points (BBP) approach. See how the core BBP principles look when applied to different topics. Get inspired by seeing how to apply new techniques to your presentation.

Ruby complains when you make an error, and here it s complaining that you can t convert a number into a string (where a string is a collection of text, such as this very sentence). Numbers and strings can t be mixed in this way. Deciphering the reason isn t important yet, but experiments such as this along the way will help you learn and remember more about Ruby than reading this book alone. When an error like this occurs, you can use the error message as a clue to the solution, whether you find it in this book, on the Internet, or by asking another developer. An interim solution to the preceding problem would be to do this:

Or this:

Although these chapters used a single presentation example, you can apply the same underlying BBP process to unlock a clear message from any topic and guide the working memory of your audience to clear and memorable understanding.

The statement for executing a string is exec: >>> exec "print 'Hello, world!'" Hello, world! However, using this simple form of the exec statement is rarely a good thing; in most cases you want to supply it with a namespace, a place where it can put its variables. You want to do this so that the code doesn t corrupt your namespace (that is, change your variables). For example, let s say that the code uses the name sqrt:
