Description: The ‘typeid’ operator in C++ is a fundamental tool that allows obtaining information about the type of an expression at runtime. This operator is part of C++’s type system and is primarily used in the context of object-oriented programming. By applying ‘typeid’ to an expression, a ‘std::type_info’ object is obtained, which contains details about the type of the expression, such as its name and characteristics. This is especially useful in situations where polymorphism is involved, as it allows identifying the actual type of an object in a class hierarchy. ‘typeid’ can be used with both built-in data types and user-defined classes and structures, making it a versatile tool for developers. Additionally, its use is safe and does not imply significant performance overhead, making it suitable for time-critical applications. In summary, ‘typeid’ is an operator that provides an effective way to obtain type information in C++, facilitating the implementation of advanced features in object-oriented programming.
