There are various types of data type such as int, char float etc. For example: int i; here variable i can store only data of integer typechar c; here variable c can store only data of character typefloat f; here variable f can store only data of floting-point type Variable of each data … Read more
Anonymous Object is a Object without any name. In C++ programming an object is created with names but It is still possible to create objects without names such objects are known as anonymous objects. When the constructor and destructor are called, the data members are initialized and destroyed respectively. Without an object, we can initialize … Read more
In a C++ programming language, a class that contains at least one pure virtual function is called an abstract class. This pure virtual function is declared within the base class and defined by a derived class. An abstract class in C++ is a class that cannot be instantiated directly and contains one or more pure … Read more
Function Overriding in C++ Programming Language is one of the important concept in C++. Function Overloading is used to achieve run time polymorphism What is Function Overriding in C++? When two classes are in the inheritance hierarchy. The parent class function is re-defined in the child class with the same method signature. The re-defined function … Read more
Array of Objects in C++ Array of Object is similar to creating array or integer, character or any primitive data types. Example Array of integer is int age[5]={1,2,3,4,5}; Similar way array of Students is Student s[5]={studentObj1,studentObj2,studnetObj3,studentObj4,studentObj5}; The student is class Name s is an array of objects of 5 elements To initialize the student object … Read more
In a C++ language we can define a class within a function and such classes are called local classes. Local Classes in C++ Inside the local class, we can access the global and static variables. Local class can’t access the normal/nonstatic variable of a function. #include using namespace std; class A { private: int x; … Read more
In C++ objects can be classified as local object and global object. Local object A object defined inside a block is called local object. A local object can be inside block or function or class In above figure variable a and b are local variable inside complex class. Inside main function Complex c=Complex(1,2); is defined … Read more
Here we will develop a C++ program for addition subtraction multiplication and division operations. following are the arithmetic operations in C++ programming. Sr No Operator Symbol Example 1 Addition + int result = num1 + num2; 2 Subtraction – int result = num1 – num2; 3 Multiplication * int result = num1 * num2; 4 … Read more
In a C++ programming language, the size of any object is equal to the sum of the size of all the class data members. In C++, the sizeof the operator returns the size of an object in bytes, including any padding added for alignment. The size of an object is determined by the sum of … Read more
In a C++ programming language, the union is a special user-defined data type that allows to the storage of different data types in the same memory location. “union” uses the same memory location for multiple-purpose. Or In a union data type, a single variable, i.e., the same memory location, can be used to store multiple types … Read more
