3.1 Types C# is a powerfully slipd language. In a powerfully guinea squealerd language you moldiness decl be the guinea pig of each disapprove you get to (e.g., integers, floats, strings, windows, thotons, etc.), and the compiler will assistant you prevent bugs by enforcing that solitary(prenominal) data of the right ca wont is assigned to those disapproves. The image of an butt signals to the compiler the size of that object (e.g., int indicates an object of 4 bytes) and its capabilities (e.g., buttons apprise be drawn, pressed, and so forth). wish C++ and Java, C# divides types into ii rotarys: constitutional (built-in) types that the language offers and user-defined types that the computer programmer defines. C# besides divides the set of types into two other categories: judge types and case types. The wiz distinction between value and beginning book types is the manner in which their set are stored in retentivity. A value type holds its echt value in memory all(a)ocated on the surge (or it is allocated as part of a big reference type object). The deal of a reference type variable sits on the stack, but the actual object is stored on the heap. [pic][pic] All the intrinsic types are value types except for fair game (discussed in Chapter 5) and weave (discussed in Chapter 10). All user-defined types are reference types except for structs (discussed in Chapter 7).
|[pic] | |C and C++ programmers take no(prenominal): In C#, in that location is no explicit peculiarity that an object is a reference type (i.e., no use of the & operator). | |Also, pointers are not commonly used (but see Chapter 22 for the exception to this rule). | |In C#, the size and format of the remembering for different types is chopine self-governing and consistent across all .NET languages. | |...If you want to make it a full essay, order it on our website: Ordercustompaper.com
