In the following program struct B defines two conversion operators: to A and to const A&. Then A-object is created from B-object: The program i ...
In the following program struct S provides two conversion operators: in double and in long long int. Then an object of type S is passed to a function ...
I have this class SmallInt that should represent a positive integer value in the range 0-255-inclusive: What matters me is: why can I assign to ...
I am trying to write a basic std::any alternative to use in my code, the reason is that i want to replace the templated std::any_cast with a conversio ...
I am writing a lightweight parser combinator library (akin to Boost::Spirit) as hobby project. One thing I'd like to do, is to automatically be able ...
The following code compiles, runs, and gives the result as if range is being converted to bool via range.empty(). Is it actually what happens? I'm rea ...
I have a class with an implicit conversion operator to a pointer. Deallocating that pointer is not valid. Can I prevent the conversion to a pointer wh ...
I'm currently learning how implicitly defined conversion operators (also known as user-defined conversions) work for a given class. In my particular c ...
I am working with some legacy code, where one of the previous developers created a Guid (Global Unique IDentifier) class that used Microsoft’s GUID st ...
Consider the following code: Is there a working alternative in C++20 to inherit and expose a templated conversion function? ...
In C++ Primer 5th Ed., Chapter 14 discusses conversion operators: Under earlier versions of the standard, classes that wanted to define a conversi ...
I would like to wrap C types into a CPP class for better memory handling. For instance the below code snippet shows roughly what I would like to do: ...
I want to check if something is valid using bool cast overload: However when I used It used int cast overload instead ...
I've encountered a discrepancy between GCC and clang (big range of versions thereof tested at godbolt - all had same discrepancy) with conversion oper ...
Consider the following: Where a and b are user defined types which returns a proxy object to delay evaluation (this is required for more complex ex ...
I have following code: This code works as intended and calls ctor and implicit conversion operator once. However if I change the signature of doso ...
I have a class wrapping an array and want to provide the typical subscript access to its users. I may both provide conversion and provide subscr ...
I have a wrapper class that should behave like a pointer. I have overloaded operator T* and operator bool. Bool does some extra validation. I tried us ...
I know while(cin) means while all previous operations on cin have succeeded, continue to loop. But what does that really mean? Does it mean "after I ...
