Description: In C++, the term ‘Non-Virtual’ refers to functions that do not use virtual dispatch, meaning they are not invoked through a virtual method table (vtable). This implies that the functions are statically bound, allowing the compiler to perform more aggressive optimizations and generate more efficient code. Non-virtual functions are typically faster than their virtual counterparts, as they do not require the overhead of looking up in the vtable to determine which function to invoke at runtime. Additionally, non-virtual functions can be easier to understand and maintain, as their behavior is predictable and does not depend on the runtime type of the object. In the context of object-oriented programming, non-virtual functions are useful when one wants to avoid the performance overhead associated with virtual dispatch, especially in situations where performance is critical. However, this also means losing the flexibility offered by polymorphism, as one cannot override a non-virtual function in a derived class. In summary, ‘Non-Virtual’ in C++ refers to a programming approach that prioritizes efficiency and simplicity over the flexibility of polymorphism.
