What are the various OOPs concepts in C++?
Classes: It is a user-defined datatype Objects: It is an instance of a class Abstraction: It is a technique of showing only necessary details Encapsulation: Wrapping of data in a single unit Inheritance: The capability of a class to derive properties and characteristics from another class PolymorphiRead more
Classes: It is a user-defined datatype
See lessObjects: It is an instance of a class
Abstraction: It is a technique of showing only necessary details
Encapsulation: Wrapping of data in a single unit
Inheritance: The capability of a class to derive properties and characteristics from another class
Polymorphism: Polymorphism is known as many forms of the same thing
What is Function Overriding?
When a function of the same name, same arguments or parameters, and same return type already present/declared in the base class is used in a derived class is known as Function Overriding. It is an example of Runtime Polymorphism or Late Binding which means the overridden function will be executed atRead more
When a function of the same name, same arguments or parameters, and same return type already present/declared in the base class is used in a derived class is known as Function Overriding. It is an example of Runtime Polymorphism or Late Binding which means the overridden function will be executed at the run time of the execution.
See lessWhat are classes and objects in C++?
A class is a user-defined data type where all the member functions and data members are tailor-made according to demands and requirements in addition to which these all can be accessed with the help of an object. To declare a user-defined data type we use a keyword class. An object is an instance ofRead more
A class is a user-defined data type where all the member functions and data members are tailor-made according to demands and requirements in addition to which these all can be accessed with the help of an object. To declare a user-defined data type we use a keyword class.
An object is an instance of a class and an entity with value and state; In simple terms, it is used as a catalyst or to represent a class member. It may contain different parameters or none.
See lessDefine token in C++
A token is the smallest individual element of a program that is understood by a compiler. A token comprises the following: Keywords – That contain a special meaning to the compiler Identifiers – That hold a unique value/identity Constants – That never change their value throughout the program StringRead more
A token is the smallest individual element of a program that is understood by a compiler. A token comprises the following:
Keywords – That contain a special meaning to the compiler
See lessIdentifiers – That hold a unique value/identity
Constants – That never change their value throughout the program
Strings – That contains the homogenous sequence of data
Special Symbols – They have some special meaning and cannot be used for another purpose; eg: [] () {}, ; * = #
Operators – Who perform operations on the operand
What are references in C++?
When a variable is described as a reference it becomes an alias of the already existing variable. In simple terms, a referenced variable is another named variable of an existing variable keeping in mind that changes made in the reference variable will be reflected in the already existing variable. ARead more
When a variable is described as a reference it becomes an alias of the already existing variable. In simple terms, a referenced variable is another named variable of an existing variable keeping in mind that changes made in the reference variable will be reflected in the already existing variable. A reference variable is preceded with a ‘&’ symbol.
See lessDefine ‘std’?
‘std’ is also known as Standard or it can be interpreted as a namespace. The command “using namespace std” informs the compiler to add everything under the std namespace and inculcate them in the global namespace. This all inculcation of global namespace benefits us to use “cout” and “cin” without uRead more
‘std’ is also known as Standard or it can be interpreted as a namespace. The command “using namespace std” informs the compiler to add everything under the std namespace and inculcate them in the global namespace. This all inculcation of global namespace benefits us to use “cout” and “cin” without using “std::_operator_”.
See lessWhat is C++? What are the advantages of C++?
C++ is an object-oriented programming language that was introduced to overcome the jurisdictions where C was lacking. By object-oriented we mean that it works with the concept of polymorphism, inheritance, abstraction, encapsulation, object, and class. Advantages of C++: C++ is an OOPs language thatRead more
C++ is an object-oriented programming language that was introduced to overcome the jurisdictions where C was lacking. By object-oriented we mean that it works with the concept of polymorphism, inheritance, abstraction, encapsulation, object, and class.
Advantages of C++:
C++ is an OOPs language that means the data is considered as objects.
See lessC++ is a multi-paradigm language; In simple terms, it means that we can program the logic, structure, and procedure of the program.
Memory management is a key feature in C++ as it enables dynamic memory allocation
It is a Mid-Level programming language which means it can develop games, desktop applications, drivers, and kernels
