Operator overloading is one of the core features of C++, essentially granting existing operators (such as +, -, *, &&, -> etc.) new behaviors— allowing custom types (such as classes and structures) to use operators like built-in types (int, double etc.), making the code more concise and intuitive. In simple terms:Operator … Read more

C++ Object-Oriented Programming: From Built-in Types to Custom Types
