C pointers arithmetic operations are different from the general arithmetic operations. The following are some of the important pointer arithmetic operations in C:Increment and Decrement of a Pointer Addition and
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. void ...
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, ...
除了使用赋值操作让一个指针引用一个给定的对象或函数,也可以使用算术运算来修改一个对象指针。当进行指针算术运算(pointer arithmetic)时,编译器会自动在运算中采用指针所指类型的空间大小。 对于指向对象的指针,可以进行下列的运算: (1)对一个指针执行整数加法和减法操作。 (2)两个指针相减。 (3)比较两个指针。

Pointer arithmetic There are four arithmetic operators that can be used in pointers: ++, --, +, - 2 Array of pointers You can define arrays to hold a number of pointers. 3 Pointer to pointer C allows you to have pointer on a pointer and so on. 4 Passing pointers to functions in...
