For up-to-date information on C++, see the main reference at cppreference.com. Operator overloading in C++ allows us to write natural expressions like d = a + b / c; with our own classes. The above expression
6.operator-> Class member access can be controlled by overloading the member access operator (–>). This operator is considered a unary operator in this usage, and the overloaded operator functionmust be a class member function. Therefore, the declaration for such a function is: class-type*o...
I have a class string that overloads operator + to accept a char* (string) and adds it at class's (char*) pointer address; My problem is i have created the overload func that adds the string from the right; But how to define if the character string is added from the left?, how...
A book I'm using, for example, says to overload the addition operator with a function that uses only one parameter, while an online resource says to create one with two. Before I get into any specific questions, does someone here have a reference source for this information? I'd like ...
When overloading operators, it’s best to keep the function of the operators as close to the original intent of the operators as possible. Furthermore, because operators don’t have descriptive names, it’s not always clear what they are intended to do. For example, operator+ might be a...
Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<
Is there any good reason we don't just make the parameters for the operator() overload size_t instead of doing 3 separate int to size_t casts? when written like this: #include <cassert> // for assert() #include <iostream> class String { private: std::string m_string{ }; public:...
I have no reason for writing that. I'm just stuck in overloading operaotors. I have no problem if I want to write that with a function. I think the problem is with the example I'm trying to write. I should write something else. ...
Operator precedence is unaffected byoperator overloading. For example,std::cout<< a? b: c; parses as(std::cout<< a)? b: c; because the precedence of arithmetic left shift is higher than the conditional operator. Notes Precedence and associativity are compile-time concepts and are independe...
