If a variable uses more than one byte of memory, for pointer purposes its address is
A) the address of the last byte of storage
B) the average of all the addresses used to store that variable
C) the address of the first byte of storage
D) the address of the second byte of storage
E) None of these

In most computer architectures, variables are stored in contiguous blocks of memory. When a variable uses more than one byte of memory, the address of the variable corresponds to the address of its first byte. Therefore, the address of the variable is the address of the first byte of storage. Choice A is incorrect because it refers to the address of the last byte, which may not be the same as the address of the variable itself. Choice B is also incorrect because there is no reason to average the addresses used to store the variable. Choice D may be true if the variable is a multi-byte integer that is stored in a non-standard order, but this is not a common scenario.
