WebApr 12, 2024 · Rc, short for “reference counting,” is a smart pointer that enables shared ownership of a value. With Rc, multiple pointers can reference the same value, and the value will be deallocated only when the last pointer is dropped. Rc keeps track of the number of references to the value and cleans up the memory when the reference count reaches zero. WebApr 8, 2024 · The find () function is a member of the string class in C++.
