If I was not asked in the fan group, I still don't know that someone would do this: class Base{ ...};class Derived : public Base{ ...};Base* bs = new Derived[10];delete[] bs; I would like to say that this is completely C ++ compatible with C language, and then the C la

A glance is a bit vague; note the difference: 　　　　1. function pointer: the type of the function return value.. 　　　Pointer function: the return value is a pointer (address) 2. Is int (* p) () the same as int * p? Why? Int (* p) () is a variable description, indicating that p is a pointer variable pointing to the functio

C ++ Pointer and Reference vomit blood arrangement pointer Reference, vomit blood Pointer Many people have a headache and confuse when talking about the pointer of C ++. It is often confused with variable names, references, etc. In fact, the main reason is that many programmers have problems with basic knowledge, resu

A null pointer is a special pointer value and the only pointer value that is valid for any pointer type. A pointer variable has a NULL pointer value, indicating that it was idle at the time and did not point to something meaningfu

First, post a document Int p; // This is a common integer variable int * p; // It starts from P and is first combined with *, so P is a pointer and then combined with int, indicates that the Pointer Points to the int type of content. so P is a pointer to return integer data, int p [3]; // starting from P, it is first combined with [], indicating that P is an arra

Induction done by others, the system is too much ~~I. Memory Allocation for pointers and heapA pointer is a type of pointer. In theory, it contains the addresses of other variables, so it is also called address variable in some books. Since the pointer is of a type and has a size, the pointer size is 4 bytes in size on

Pointer is a pointer, pointer variable in the system, will always account for 4 byte , its value is the address of a certain memory. The pointer can point to anywhere, but not anywhere you can access it through this pointer variable. an array is an array whose size is re

The analysis principle of pointer variables: from the variable name, according to the operator priority combination, step-by-step analysis.

One: Memory allocations for pointers and heapspointer array : A pointer is placed in an array, and we call him an array of pointers.int * A[10]; Since it is an array, he cannot apply for space from the heap space. can only be a loop, each element to apply for space, or each element to point to another address space. array pointer : A pointer to a single or multi

Today we are going to learn a pointer called "pointing to another pointer address." Let's review the con
