`&`：地址运算符，获取变量内存地址；`*`：解引用运算符，访问指针指向的值；指针算术：指针加减整数实现内存地址移动。`&`: Address operator, gets variable's memory address ;`*`: Dereference operator, accesses value pointed by pointer ;Pointer arithmetic: Adding/subtracting integers to move memory a...
Pointer Arithmetic Here, we have a simple program to illustrate the concepts of both incrementing a pointer and using a compound assignment operator to jump more than one element in the array. First, we initialize the pointer p to point to the array x. In this case, we are initializing th...

http://stackoverflow.com/questions/3523145/pointer-arithmetic-for-void-pointer-in-c When a pointer to a particular type (say int, char, float, ..) is incremented, its value is increased by the size of that data type. If a void pointer which points to data of size x is incremented, ...
because the array name alone is equivalent to the base address of the array. val==&val[0]; 3) In the loop the increment operation(p++) is performed on the pointer variable to get the next location (next element’s location), this arithmetic is same for all types of arrays (for all...
指针链 / Pointer chains 指针链经常被用来访问结构体的信息,比如,下面的这段常见的代码: typedef struct { int x, y, z; } Point3; typedef struct { Point3 *pos, *direction; } Object; void InitPos1(Object *p) { p->pos->x = 0; p->pos->y = 0; p->pos->z = 0; } 代码中,处理...
Void pointers can point to any memory chunk. Hence the compiler does not know how many bytes to increment/decrement when we attempt pointer arithmetic on a void pointer. Therefore void pointers must be first typecast to a known type before they can be involved in any pointer arithmetic. ...
