As the name implies (?) Similar to a monotonic stack? Maintain a monotonically decreasing stack. Once the element that is ready to stack is larger than the top of the stack, the stack pops up until the element that is ready to stack is less than or

polymorphic compile-time polymorphism: overloading Run-time polymorphism: virtual function. The locates the correct virtual function by obtaining the correct virtual pointer based on the class of the runtime.

After a cursory reading of the book "Deep Exploration of the C + + object Model", there is some understanding of the underlying memory layout of C + + objects, but at the same time, there are some doubts:1, after the sub-class pointer with

This is what I wrote a year ago. A code that simulates a post-submission form in C # is now recorded below to avoid forgetting. At that time just learned c#~ flowing away quickly. Very unfamiliar. The code looks very childish and bloated.#region
