C++ Operator Overloading. C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. Operator overloading is a compile-time polymorphism. For example, we can overload an operator '+' in a class like String so that we can concatenate two strings by just using +. Other ...

BetaThings to Remember in C++ Operator Overloading. 1. By default, operators = and & are already overloaded in C++. For example, we can directly use the = operator to copy objects of the same class. Here, we do not need to create an operator function. 2. We cannot change the precedence and associativity of operators using operator overloading. 3 ...

BetaThese are the lists of a few excluded operators and are very few compared to large sets of operators that can be used for operator overloading. An overloaded operator is used to operate on the user-defined data type. Let us take an example of the addition operator (+) operator that has been overloaded to perform addition on various variable ...

BetaOperator Overloading (I) Mechanism in which we give an additional meaning to existing operators when they are applied to user defined data types e.g. objects When an operator is overloaded, its original meanings are not lost Improves readability of code and increases scope of operator.

BetaBeginning the OO functionality part of the class definition, we add support for += (lhs = lhs + rhs), -=, and unary -(negation). Note that the signature for operator+= and operator-= is the same for the special member function operator=, that is: taking a parameter of type const Vec3d& and returning a reference to *this. (In these member functions, as with the others, a Vec3d<T> is implied by ...

BetaOperator overloading means that the operation performed by the operator depends on the type of operands provided to the operator. For example, (a) the bit left-shift operator << is overloaded to perform stream insertion if the left operand is a ostream object such as cout; (b) the operator * could means multiplication for two numbers of built-in types or indirection if it operates on an address.

BetaOperator overloading in C++ is done by programmers to redefine the standard operators without changing their original meaning, which enhances code reusability, readability, and efficiency. Also, it helps in performing operations on complex numbers and custom memory management. In this article, we will discuss operator overloading in C++, types of overloading in C++, the difference between ...
