If I am just expressing text with no escape characters or anything strange I can tell the compiler that this is a verbatim string. I do this by putting an @ in front of the literal: @"\x0041BCDE\a" If I print this string I get: \x0041BCDE\a This can be useful when you are expressing things like file paths. The verbatim character has another trick, which is that you can use it to get string literals to extend over several lines: @"The quick brown fox jumps over the lazy dog" This expresses a string which extends over three lines.

And so we use the second closing brace to mark the end of the class itself. Programmer’s Point:Program layout is very important You may have noticed the rather attractive layout that I have used when I wrote the program. Items inside braces are indented so that it is very clear where they belong. I do not do this because I find such listings artistically pleasing. I do it because otherwise I am just about unable to read the program and make sense of what it does. JustlikeIfindithardtoreadenglishwithouttheproperspacing I find it hard to read a program if it has not been laid out correctly.

Both conform to a pattern of behaviour (read data in, process it, print it out) which is common to many applications. Any time that you are asked to write a program that reads in some data, works out some answers and then prints out the result you can make use of this pattern. Part of the skill of a programmer is identifying the nature of a problem in terms of the best pattern to be used to solve it. Writing a Program The programs that we have created up until now have been very simple. They just read data in, do something with it and then print out the result.
