C++ Inheritance & Polymorphism: Constructors, Destructors, & Inheritance
Price on Request
1 hour 25 minutes
The order in which constructors and destructors are invoked on an object of a derived class in an inheritance hierarchy is a very important topic. Constructors are invoked in order from the top-most (most base-level) class, down to the most derived class. Destructors are invoked in the reverse order. Explore how constructors work in an inheritance hierarchy, the order in which the base and derived class constructors are invoked, and how initialization lists need to be used in the derived class. Discover how to use copy constructors and destructors in the context of inheritance. Learn how to set up an inheritance hierarchy for polymorphism. Finally, practice using objects in an inheritance hierarchy with variables of pointer and reference types. When you finish this course, you will have a solid foundation in constructors, destructors, and inheritance, setting the stage for runtime polymorphism and dynamic method dispatch.

C++ Inheritance & Polymorphism: Multiple Inheritance & the Diamond Hierarchy
Price on Request
1 hour 20 minutes
C++ allows multiple inheritance, which means that one class can have more than one base. C++ also has some powerful mechanisms for dealing with edge cases such as the diamond hierarchy. You will start this course by learning the precise syntax which is required to implement multiple inheritance in C++, specifically, how it's important to have both base class access specifiers marked independently. You will then move on to the topic of a diamond inheritance hierarchy, in which the grandchild-level derived class has two parents, both of which inherit from the common, grandparent level base class. Finally, you will see how dynamic casts work in the context of an inheritance hierarchy, how these are a lot safer than static casts, and how they return a null value on failure when used with pointers but they throw an exception on failure when used with references.

C++ Inheritance & Polymorphism: Pure Virtual Functions & Abstract Classes
Price on Request
1 hour 20 minutes
Pure virtual functions and interfaces are very powerful tools in object-oriented programming, and interface-driven programming is a great way of splitting up work across different developers on a large project. You will start this course by considering why your destructors should be marked as virtual in the base class if you have an inheritance hierarchy. You'll see the harmful effects of not using virtual destructors in an inheritance hierarchy and the problems with object slicing. You will also learn why it is preferable to have variables of reference types to the base class rather than the value types. You will then move to some finer points of working with virtual methods, such as, the inadvisability of using default parameters because these are statically bound. Finally, you will master the syntax and semantics of pure virtual functions and learn how a class that contains even one pure virtual function becomes an abstract class that cannot be instantiated directly.

C++ Inheritance & Polymorphism: Understanding & Using Polymorphism
Price on Request
1 hour 30 minutes
Inheritance forms the basis for polymorphism, specifically runtime polymorphism, which is a powerful object-oriented programming construct. Runtime polymorphism involves a pointer or a reference of the base class type holding an object of the derived class. The beauty of runtime polymorphism is that when virtual methods are invoked on this pointer, the derived class versions are executed. You will start this course by defining name hiding and how most methods on C++ objects are, by default, statically dispatched. You will then learn about polymorphism and dynamic dispatch, which is accomplished using the virtual keyword. Finally, you will learn how the ‘override' and 'final' specifications can be used to achieve precise semantics and reduce the scope of bugs and typos in your C++ programs.

C++ Inheritance & Polymorphism: Using Inheritance for is-a Relationships
Price on Request
1 hour 30 minutes
Inheritance is a powerful, object-oriented language construct in which one class can be related to another class using an is-a relationship. Using inheritance, you can construct complicated class hierarchies in which one class is a parent or a base of another class. Is-a relationships are a great way of performing object-oriented design and are complemented by has-a relationships, which are implemented using composition, rather than inheritance. Explore inheritance relationships by setting up an inheritance hierarchy in C++ and specifying one class as the parent of another class. Then discover how member variables and methods are accessible from the drive class, as well as from external code. Finally, investigate base class access specifiers, and find out how they work with member access specifiers. When you're finished, you'll clearly understand how to use inheritance for is-a relationships and how to identify uses for private inheritance.

Classes in Java: Implementing Functional Interfaces Using Lambdas
Price on Request
1 hour 30 minutes
Lambda expressions allow you to define classes that implement single-method interfaces in a very concise and compact manner. This makes code that uses lambda functions easier to read and understand and much more maintainable. Lambda expressions can be made even more compact and readable by the use of method references. In this course, you will learn to create and use lambda expressions to implement functional interfaces. You will see that lambda expressions are essentially blocks of code that accept input arguments, perform operations, and return values. Lambda expressions can be used in any place where we use anonymous classes or a named class that implements an interface with just a single abstract method. You will see that lambdas can only be used to implement functional interfaces i.e. interfaces that have exactly one abstract method. Such interfaces are usually annotated using the @FunctionalInterface annotation which allows the compiler to detect if the single abstract method contract has been violated for such interfaces. You will understand and implement the four types or categories of functional interfaces, the Predicate, Function, Consumer, and Supplier interfaces. Finally, you will round this course off by exploring and implement method references which are essentially even more compact representations of lambda expressions. When you are finished with this course you will have the skills and knowledge to construct lambda expressions in the right way and use Predicates, Functions, Suppliers, and Consumers to process and store your objects.

Control Structures in C: Getting Started with Control Structures
Price on Request
1 hour 55 minutes
A control structure in C is any code construct that changes the flow of control, such as the order of execution in a program. The three main types of control structures in C are decision-making control structures, looping control structures, and unconditional control structures. Decision-making control structures include if-else blocks and switch statements. You will start this course by working with the if statement control structure. This checks whether a condition is satisfied or not, and returns an output based on that. You will then use the if-else-if ladder to create multiple conditions that will be checked in order. The code block associated with the first condition that is satisfied will be executed, and subsequent conditions will not even be checked. Finally, you will learn about the ternary operator, which makes use of the ? and : symbols to create an if-else block and store the result in a variable. Upon completion of this course, you'll be able to work with control structures to change the flow of execution of a C program, use if and else conditions, and employ the ternary operator in assignments and expressions
