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, ...
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. ...
constintarray_size=3;intia[array_size]={0,1,2}; If we explicitly specify a list of values, we may not specify the size of the array: the compiler itself will count the number of elements. C++ Pointer A pointer is an object containing the address of another object and allowing indirect...
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...
The correspondence between indexing and pointer arithmetic is very close. By definition, the value of a variable or expression of type array is the address of element zero of the array. Thus after the assignment pa = &a[0]; pa and a have identical values. Since the name of an array is...
Thenia(number_in_array) variable is required so that the size of the array is known. Note that only a pointer to the array, rather than the contents of the array, is passed to the function. Also note that C functions can accept variable-size arrays as parameters....
