Chapter 7, Problem 23RQ

There are no limitations on the implementation of an overloaded operator. Falsely Precise

what is the advantage and disadvantage of overloading operators? ( please tell in simple language which I can learn).

Regarding the type declaration, what is it that differentiates a rvalue reference from a lvalue reference?

Explain how coercion rules can weaken the beneficial effect of strong typing.

Operator overloading is     extremely common in PL since + works differently for ints and floats and it is also common for programming languages to allow the developer to overload operators     very uncommon in programming languages but some languages allow the programmer to overload all operators     very uncommon in programming languages     extremely common in PL since + works differently for ints and floats but it is uncommon for programming languages to allow the developer to overload operators

The C struct, Exercise  In C++: The programming assignment at the end of this module will involve a struct named Square with exactly one attribute representing the length of one of its sides as a numeric data type. Square objects will have exactly one supporting function to calculate the area and perimeter of a Square object, with two parameters -- an ostream object by reference, and a Square by constant reference. The function should send to the ostream object: the side's value, labeled without rounding, followed by the area and perimeter, both labeled and rounded to two decimal digits. (Note that this function may be called several times from a main program, and still the side should be output with any formatting removed!) Write two code blocks -- one for the struct and its supporting function's prototype, and another for the function definition itself. Assume that all needed library includes have already been made. Do not write a full working program or int main() -- just…

I am studying overloaded operators like assignment and array subscript operators and how the must be members of that class, which confuses me some. Why are these overloaded operators required? What are their reasons and purpose inside code?

How to use Nullable<> Types in C#?

The assignment operator (=) and the equivalence operator (==) are interchangeable, but they will perform either the function of assignment or equivalence depending on the context in which they are used. O True O False
