I saw this question in Baidu just now and answered it. This is a good question. Let's summarize it. Declare a two-dimensional array int matrix[100][100]; When two-dimensional arrays are passed as parameters, many people may write intfun (INT **

PS : Const object can only be called Const Function!! Non- const objects casually!! Member pointers are applied only to non- static members of the class. The static class member is not part of any object, so no special syntax is required to point to

Const pointer and pointer to const There are two meanings when using a pointer with Const. One means that you cannot modify the content of the pointer, And the other means that you cannot modify the content pointed to by the pointer. It sounds a

Pointer to class members, which is rarely used in the impression. When I re-learn C ++, I found that I ignored a very important thing, I used to think that the member functions of the class cannot be used as Callback functions. Therefore, many C

"Reference in standard containers" and "pointer to reference )" As we all know, standard containers store and manipulate the instances stored in them by value and do not allow the storage of reference in standard containers" . Vector ; After

Recently, function pointers have been used in development, so I want to sort out the concept of function pointers. O (distinct _ distinct) O ~ First, the function pointer is a pointer to a group of functions of the same type. We can also think

To illustrate:function declaration: void Fun (int (*p) [4]);void Fun (int (*p) [4]){int i=0,j=0;for (i=0;ifor (j=0;jcout }P is a pointer to a[0], then P+i is a pointer to A[i], * (p+i) is a pointer to a[i][0],Then * (p+i) +j is a pointer to a[i][j],

Array pointers: First look at the name "array pointer" is "pointer", it can be understood as a pointer. But there is an array in front of it, that is, it points to an array.See-"Int (*p) [Ten], we parse from an expression, because () has a high

A pointer pointing to any object type can be assigned to a variable of Type void *, void * can be assigned to another void *, and two voids * can be equal or not, in addition, you can explicitly convert void * to another type. Other operations are
