Web7 apr. 2024 · You could extend the preceding example by defining an implicit conversion from int to Fraction. Then, overloaded operators would support arguments of those two types. That is, it would become possible to add an integer to a fraction and obtain a fraction as a result. You also use the operator keyword to define a custom type conversion. WebSee also operator++(). const_iterator const_iterator:: operator--(int) This is an overloaded function. The postfix --operator (i--) makes the preceding item current and returns an iterator pointing to the previously current item. const T *const_iterator:: operator-> const.
