Operators in C++ Scope Resolution Operator (::) Memory Allocation/De-allocation operator (new and delete) Member Access operators (->,.*, ->*,.) Reference Operator ( & ) Insertion and Extraction Operators (<< and >> ). .
Scope Resolution Operator (::) Used for resolving the scope of the variables . Used for defining methods outside the class declaration .
Reference Variables Reference variable is an alias created for an already existing variable Change in reference will change the value of the variable and vice versa Should be initialized when declared and cannot be reinitialized A variable can have multiple reference Array of reference is not allowed
Functions - Pass By Pointer & Pass by Reference Referencing Offers a clean, elegant and efficient way to pass parameters to functions that changes the value of actual parameter Difficulty in de-referencing is eliminated in pass by reference Calling syntax is much simpler compared to call by address Pass by Reference needs no memory .
Abstract Data Types (ADTs) Abstraction of data structures results in ADTs . They are partial solution to modelling a problem. . The closest to abstract data type in C is structures . In C++ it is implemented using 'Classes'
An ADT is a model of a data structure that is characterized by the following properties It has a type. It has a set of operations. This set is called an interface. In object oriented terms the set of operations define the behavior of the object Operations of the interface are the only access mechanism to the type's data structure Specifies what each operation does, but doesn't reveal how any given operation works
Structures in C Composite data type Contains one or more logically related data (similar or dissimilar) grouped together under a single name for convenient handling Variables declared inside structure are called fields or members Functions cannot be part of Structure . . . re variables can be created using structure name. Members can be accessed using <Structure variable Name> <Member Name>
