Format: PDF / Kindle (mobi) / ePub
Only Doyle's C# PROGRAMMING: FROM PROBLEM ANALYSIS TO PROGRAM DESIGN, 4E brilliantly balances today's most important programming principles and concepts with the latest insights into C#. This perfect introductory book highlights the latest Visual Studio 2012 and C# 4.0 with a unique, principles-based approach to give readers a deep understanding of programming. You'll find just the right amount of detail to create an important foundation in programming. This edition's straightforward approach and understandable vocabulary make it easier for readers to grasp new programming concepts without distraction. The book introduces a variety of fundamental programming concepts, from data types and expressions to arrays and collections, all using the popular C# language. New programming exercises and new numbered examples throughout this edition reflect the latest updates in Visual Studio 2012, while learning objectives, case studies and Coding Standards summaries in each chapter ensure mastery. While the book assumes no prior programming knowledge, coverage extends beyond traditional books to cover new advanced topics, such as portable class libraries used to create applications for Windows Phone and other platforms.
W in “World.” The output for both of the preceding segments of code is: Hello World! Usually, the characters inside the double quotes are displayed exactly as they appear when used as an argument to Write( ) or WriteLine( ). An exception occurs when an escape character is included. The backslash ( '\' ) is called the escape character. The escape character is combined with one or more characters to create a special escape sequence, such as '\n' to represent advance to next line, and '\t' for a
sequences. The backslash is not printed. When the '\n' is encountered, the output is advanced to the new line. The space between the words “come” and “down” was placed there as a result of the tab escape sequence ('\t'). Two other methods in the Console class, Read( ) and ReadLine( ), deserve explanation.Visually they differ from the WriteLine( ) method in that they have no arguments—nothing is placed inside the parentheses. Both the Read( ) and ReadLine( ) methods can return values and are used
