Get Beginning C# 2008 Objects: From Concept to Code (Expert's PDF

By Grant Palmer

I'm really not but performed examining this publication. So for now i must supply it three stars. however the cause i am posting the reason is, i actually used to be surprised at p.13. On that web page they're telling you to initialize variables with "" and there's no point out of initializing them with string.empty that is simply most sensible practice!

Even Microsoft tells you here, that you can be utilizing string.empty. i suppose i don't know how three authors who declare to be specialists in C# can leave out whatever to primary and it really is anything solid quantity of builders recognize out there.

That's excited by now. i will not touch upon the remainder yet i'm going to come again right here and provides a whole assessment. I simply desired to positioned that in the market for now...kinda frightening to be interpreting a booklet the place they cannot even let you know how you can set string defaults competently.

Why C#? We could walk you through building the SRS using any OOPL. Why might we want to use C#? Read on and you’ll quickly see why! Practice Makes Perfect The designers of C# were able to draw upon the lessons learned from other OOPLs that preceded it. They borrowed the best features of C++, Java, Eiffel, and Smalltalk, and then added some capabilities and features not found in those languages. Conversely, the features that proved to be most troublesome in earlier languages were eliminated. As a result, C# is a powerful programming language that is also easy to learn.

In addition to the simple assignment operator, =, there are a number of specialized compound assignment operators, which combine variable assignments with an operation. The compound assignment operators for arithmetic operations are as follows: += a += b is equivalent to a = a + b -= a -= b is equivalent to a = a - b *= a *= b is equivalent to a = a * b /= a /= b is equivalent to a = a / b %= a %= b is equivalent to a = a % b CHAPTER 1 ■ A LITTLE TASTE OF C# ■Note The compound assignment operators don’t add any new functionality; they are simply provided as a convenience to simplify code.

Note In subsequent chapters, we’ll refine the rules for naming variables as we introduce additional object concepts. For example, the following variable names follow the C# variable naming conventions: int grade; double averageGrade; string myPetRat; bool weAreFinished; Recall that, as mentioned earlier, a C# keyword can’t be used as a variable name: int float; // this won't compile—"float" is a keyword Variable Initialization and Value Assignment There are different types of variables in C# based on how and where the variables are declared in the program.
