An operator is a symbol that tells the compiler to perform specific mathematical, logical calculations or some other special operations. The process of having two or more functions with the same name but with different parameters arguments is called function overloading. The function is redefined by either using different types of arguments or a different number of arguments.

It is only through these differences that a compiler can differentiate between functions. The mechanism of giving special meaning to an operator is known as operator overloading.

Friend function: It is a non-member function of a class with permission to access both private and protected members. Which operators Cannot be overloaded? 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.

The operators other than listed above can be overloaded either as a member or as non-members. But in general, non-member overloading is recommended. You cannot overload function declarations that differ only by return type. Thus, a programmer can use operators with user-defined types as well. Overloaded operators are functions with special names: the keyword "operator" followed by the symbol for the operator being defined.

Like any other function, an overloaded operator has a return type and a parameter list. Most overloaded operators may be defined as ordinary non-member functions or as class member functions. Following is the example to show the concept of operator over loading using a member function. I'm basing that on the would-be transitive result of such an interpretation the whole universe is syntactic sugar.

I would certainly not call const "syntactic sugar". But I confess I haven't read the strict definition in a while. Show 2 more comments. There is no operator overloading in C. Justin Ardini Justin Ardini 9, 2 2 gold badges 37 37 silver badges 46 46 bronze badges.

What it doesn't support is adding any overloads beyond what's built in. You cannot overload these operators in C. C does not support operator overloading at all.
