Is it possible to overload an operator?
Also, All operators that can be overloaded must have at least one argument that is a user-defined type. That is, operator overloading can apply only to your own classes. That means you can't overload operator+ for int or double. That means you can'toverload the scope resolution operator since it has no arguments.

How many times can a function call operator be overloaded?
In fact, the function call operator may be overloaded several times within the same scope with a different number (and/or type) of arguments. ?It is useful for accessing elements from a multi- dimensional array: matrix (row, col) where the [] operator cannot help out as it takes 2 operands always, never 3!
What is binary operator overload resolution?
For an operation of the form x + y, binary operator overload resolution (§14.2.4) is applied to select a specific operator implementation. The operands are converted to the parameter types of the selected operator, and the type of the result is the return type of the operator. The predefined addition operators are listed below.
