Is user-defined operator overloading good or bad?

In general it is not a bad thing. New languages such as C# also have operator overloading. It is the abuse of operator overloading that is a bad thing. But there are also problems with operator overloading as defined in C++.

What are the restrictions and limitations in overloading operators?

1) Only built-in operators can be overloaded. New operators can not be created. 2) Arity of the operators cannot be changed. 3) Precedence and associativity of the operators cannot be changed.

What is user-defined operator overloading?

Operator overloading is a technique by which operators used in a programming language are implemented in user-defined types with customized logic that is based on the types of arguments passed. This helps user-defined types to behave much like the fundamental primitive data types.

Why readability is important in programming language?

Code readability is one of the most important qualities of good code, like the art of writing code it’s a subjective topic which varies between developers. If code is easy to read, it will be easy to understand which makes it easy to debug, maintain and extend.

Why operator overloading is not possible in Java?

Java doesn’t supports operator overloading because it’s just a choice made by its creators who wanted to keep the language more simple. Operator overloading allows you to do something extra than what for it is expected for. Java only allows arithmetic operations on elementary numeric types.

Why do you think overloading operators might be helpful?

By overloading the operators, we can give additional meaning to the operators like +-*/=.,= etc., which by default are supposed to work only on standard data types like int, float, char, void etc. It’s a type of polymorphism in which an operator is overloaded to give it the user-defined meaning.

What are the limitations of operator overloading?

Following are some restrictions to be kept in mind while implementing operator overloading.

• Precedence and Associativity of an operator cannot be changed.
• Arity (numbers of Operands) cannot be changed.
• No new operators can be created, only existing operators can be overloaded.
• Cannot redefine the meaning of a procedure.

What are the disadvantages of operator overloading in C++?

Introduction to Operator Overloading Operator overloading is one of the best features of C++. By overloading the operators, we can give additional meaning to the operators like +-*/=.,= etc., which by default are supposed to work only on standard data types like int, float, char, void etc.

What is operator overloading Why is it necessary to overload an operator?

The need for operator overloading: It allows us to provide an intuitive interface to our class users, plus makes it possible for templates to work equally well with classes and built-in types. Operator overloading allows C++ operators to have user-defined meanings on user-defined types or classes.

What is operator overloading What are the rules of operator overloading?

Rules for operator overloading in C++ Only built-in operators can be overloaded. If some operators are not present in C++, we cannot overload them. The overloaded operator cannot hold the default parameters except function call operator “()”. We cannot overload operators for built-in data types.

What do you understand by program readability?

Readability means how easy the computer program is to understand. Any program that ends up to production should ultimately be readable. Readable programs are more valuable than their unreadable counterparts because: They require less maintenance.
