This means that the size of the variable can be determined at runtime, rather than being fixed at compile time. This is useful when you don't know the size of the variable beforehand, or when you need to allocate memory based on user input or other runtime Show more…

QUESTION 24 The C++ operator "new" is used to create dynamic variables by dynamically allocating memory. This allows for the creation of variables whose size can be determined at runtime. The "new" operator is often used in conjunction with the "delete" operator to deallocate the memory once it is no longer needed. Another important use of the "new" operator is in creating objects of classes, where it is used to allocate memory for the object and call its constructor. The "new" operator can also be used to allocate memory for arrays, in which case it returns a pointer to the first element of the array.
