All types of arithmetic operations are impossible with a pointer. The only valid operations that can be performed are as-1. Addition of integer to a pointer and increment operations.2. Subtraction of an integer from a pointer and decrement operations.3. Subtraction of a pointer from another pointer of same typepointer arithmetic is somewhat different from ordinary arithmetic. Here all arithmetic is performed relative to the size of basic type of pointer.For example, If we have an integer pointer pi which contains address 1000, then on incrementing...
