A class destructor is a special member function in object-oriented programming that is invoked when an object goes out of scope or is explicitly deleted, ensuring the release of resources and cleanup of memory. Destructors are crucial in preventing resource leaks and undefined behavior by properly managing dynamic memory and other resources acquired during the object's lifetime.

Object-oriented programming (OOP) is a programming paradigm centered around the concept of objects, which are instances of classes, encapsulating data and behavior together. This approach promotes code reusability, scalability, and organization through principles such as inheritance, encapsulation, polymorphism, and abstraction.

Undefined behavior in programming occurs when the code executes in a way that is not predictable or specified by the language standard, often leading to unpredictable results or system crashes. It is a critical concept in programming languages like C and C++, where certain operations can lead to undefined behavior if not handled correctly, making it essential for developers to understand and avoid these pitfalls to ensure program stability and security.

Dynamic memory refers to the allocation and management of memory at runtime, allowing programs to use memory efficiently based solely on current requirements rather than pre-determined limits. This flexibility is crucial for applications that need to handle varying amounts of data or optimize resource usage, making it an essential concept in modern computing systems.
