Syntax of Typecast Operator Overloading

class ClassName {
private:
    // All private members
public:
    //All  public members, constructors, etc.
    // Typecast operator overloading
    operator TargetType() const {
        // Conversion logic 
    }
};

In C++, the typecast operator can be overloaded to customize the behavior of casting operators to define how user-defined data types can be converted into other types. This enables developers to define how instances of a class are converted to other types, providing more control over implicit type conversions.

By overloading typecast operators, developers can seamlessly integrate custom classes into existing code, allowing for smoother interactions between user-defined and built-in data types.

What are Typecast Operators in C++?

The typecast operator in C++ allows developers to convert one data type to another. It is denoted by the use of parentheses followed by the target data type. For example, (int) 3.14 explicitly casts the floating-point number 3.14 to an integer.

C++ provides the following types of typecast operators:

1. static_cast
2. dynamic_cast
3. const_cast
4. reinterpret_cast
