Cast operator cppreference, If a pointer to object is cast to pointer to any character type the result points at the lowest byte of the object and may be incremented up to sizeof the target type in other words can be used to examine object representation or to make a copy via memcpy or memmove Any pointer to function can be cast to a pointer to any other function
C TypeCasting GeeksforGeeks
Typecasting in C is the process of converting one data type to another data type by the programmer using the casting operator during program design In typecasting the destination data type may be smaller than the source data type when converting the data type to another data type that s why it is also called narrowing conversion Syntax
C Cast operator overloading and references Stack Overflow, C allows for overloading type casts by creating an operator T where T is the type we want to cast to Now how does this feature play together with references For example struct Y int i struct X Y y operator Y const return y Here we can cast an X to Y which will simply return the contained Y

Converts between types using a combination of explicit and implicit conversions it cannot be compiled If there is exactly one expression in parentheses this cast expression is exactly equivalent to the corresponding C style cast expression a prvalue otherwise In the case of an ambiguity between an expression statement with a function Explicit type conversion cppreference. The value of the function call operator is the return value of the function called with the provided arguments The parameters to the function are copied on the stack by value or at least the compiler acts as if that is what happens if the programmer wanted the parameter to be copied by reference then it is easier to pass the address of the To overload the function that casts our class to an int we write a new function in our class called operator int Note that there is a space between the word operator and the type we are casting to Such functions must be non static members
