Example text

The result would be 26. You can use parentheses to change the precedence of operations: (6 + 4) * 5 In this expression, the addition is evaluated first because the parentheses have higher precedence than the other operators. The addition evaluates to 10, which is multiplied by 5, giving the result 50. 0; These operators are called binary operators because they operate on two operands. 3-6-2 The Modulus Operator (%) The modulus operator (%) is used to get the remainder of division. For example, the following expression: 5 % 2 gives the result 1, while the expression: 4 % 2 gives the result 0.

It is similar to pointers and references in C++, but much easier to use. The variable itself lives on the stack, like a value-type variable, but points to its data that lives on the heap. Note The heap is the region in memory that stores the data pointed to Ü by the reference-type variables. 3-4-1 The C# Reference Types The following are the C# reference types: n Class n Interface n Delegate n Object n String It is possible to convert value types to reference types by using boxing and from reference types to value types by using unboxing.

10 Global variables and methods Not permitted in C#. Variables and methods must be declared inside a class or struct. 2 Header files There are no header files in C#. You can use preprocessor directives in conditional compilation. You can also use the using directives to reference types in namespaces to avoid using fully qualified names. 2 and 7 Inheritance There is no multiple inheritance in C#. You can only inherit from one class. 5 Initialization list Not in C#. Instead, use constructors to build the inherited class.
