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 ...
Arithmetic can be performed on pointers. However, in pointer arithmetic, a pointer is a valid operand only for the addition(+) and subtraction(-) operators. An integral value n may be added to or subtracted from a pointer ptr. Assuming that the data item that ptr points to lies within an...

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, ...
C++ Program - Pointer ArithmeticC Program Pointer Arithmetic
Few rules about C pointers 1) A pointer variable does not store value directly just like int, float variables. A pointer store only reference (memory address) of another variable. Consider the following code intx=100;int*ptr;ptr=&x; ...
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...
