int arr[4]; Arr is equivalent to a pointer constant, and ARR cannot change, but the data that points to the address can be changedint *p = arr; P is a pointer to the int data, and the step size is sizeof (int)Arr and &arr:-Same value-Different

C + + provides the Qsort function to sort the data fast, and it provides the sort function for sorting vectors and lists, and comparing the parameters of function and function types is the key to sorting functions.#include #include #include #include

The singleton mode, also known as the single-piece mode and the list mode, is one of the most widely used design patterns. The intent is to ensure that a class has only one instance and provides a global access point to access it, which is shared by
