a) Given the variable int number, use an operator to access the address of number.

b) Given the variable int *i_ptr, use an operator to access the value stored at the location pointed to by the pointer.

c) Show two ways to obtain the address of the first element of the array data[].

d) Assume data[] contains 10 ints. Write code that will calculate the amount of memory needed by data[]. Store that value in the variable mem_size.
