What Are the Differences When We Overload a Pre Increment and Post Increment Operator

What is the difference between pre increment operator and post increment operator in C? Pre increment operator is used to increment variable value by 1 before assigning the value to the variable. Post increment operator is used to increment variable value by 1 after assigning the value to the variable.

How do we differentiate between prefix and postfix increment operator while overloading them?

If the overloaded operator has an int parameter, the operator is a postfix overload. If the overloaded operator has no parameter, the operator is a prefix overload.

Can we overload increment operator?

The postfix increment operator ++ can be overloaded for a class type by declaring a nonmember function operator operator++() with two arguments, the first having class type and the second having type int . Alternatively, you can declare a member function operator operator++() with one argument having type int .
