C# is an intuitive object-oriented programming language that could be used for writing .NET net or Windows-based functions. Assuming no previous programming event at the a part of the reader, this primer makes a speciality of the basics of composing code with C#. It starts off with variables and ends with a software that performs track (in the foremost of C#, no less). issues comprise, for instance, statement statements, Boolean variables, example equipment, and operator overloading.

Assignment operators are the only operators that associate from right to left, which means that multiple assignment operators in a row will be evaluated beginning with the rightmost. Consider the following perfectly legal statement: AÂ =Â BÂ =Â CÂ =Â 27; Because the assignment operation associates from right to left, C is first assigned a value of 27, then B is assigned the value of C, and finally A is assigned the value of B. Hereâ s another example of a legal statement: CÂ =Â (AÂ =Â 5)Â +Â (BÂ =Â 6); The first set of parentheses forces A to be assigned a value of 5; the value of the assignment expression is also 5.

The operation is now between two 32-bit signed integers, so the result is an int and the assignment is fine. Casting is represented in the Operator Precedence and Associativity table, located on the inside back cover of this book, by (type)x and is grouped with other unary operators. The problem with casting is that it may result in bits being lost. If you cast an int to a byte, for example, all the bits except the lowest 8 are simply discarded. In such a case, the cast will raise an exception at runtime only if youâ ve enabled overflow checking.

Now when the HowHigh program runs, it displays the first five lines and then raises an exception. Just as with the DividebyZero program in Chapter 6, a dialog box appears, this time reporting an overflow exception. Click No to see the error described on the console as the program is terminated. You can also perform overflow checking for individual expressions right in the source code by using the checked operator. The statement BÂ =Â checked(5Â *Â A); will raise an exception if the multiplication results in an overflow regardless of the compiler option.
