C++ Operator Overloading: A Comprehensive Tutorial

Operator overloading is a powerful feature in C++ that allows you to redefine the behavior of standard operators like `+`, `-`, `*`, `/`, `==`, `!=`, `[]`, ``, ``, and more for user-defined types (classes). This enables you to use these operators in a natural and intuitive way with your custom objects, making your code more readable and expressive.

*Why Use Operator Overloading?*

1. *Improved Readability:* Instead of writing verbose function calls like `complexNumber1.add(complexNumber2)`, you can simply use `complexNumber1 + complexNumber2`, which is much cleaner and easier to understand.

2. *Intuitive Syntax:* Overloading operators makes working with user-defined types more like working with built-in types. This reduces the learning curve for others using your code and makes the code itself more self-documenting.

3. *Code Reusability:* By defining operator behaviors within your classes, you can reuse these operations in multiple parts of your code, reducing redundancy.

*Fundamentals of Operator Overloading*

*Operator Functions:* Operator overloading is achieved by defining special functions called "operator functions." These functions have a specific name format: `operatoroperator`, where `operator` is the operator you want to overload (e.g., `operator+`, `operator==`, `operator`).

*Syntax:*



`ReturnType`: The data type that the operator returns (e.g., `ClassName`, `bool`, `int`).
`operatoroperator`: The name of the operator function.
`Parameters`: The arguments that the operator takes. The number and types of parameters depend on whether the operator is unary (operates on one operand) or binary (operates on two operands), and whether it's a member function or a non-member function (friend function).

*Member vs. Non-Member (Friend) Functions:* Operator functions can be defined as either:

*Member functions:* Defined within the class d ...
