Accepted Answer

A) True

Accepted Answer

A)  int milesAddr&;
B)  int milesAddr*;
C)  int *milesAddr;

Question 17

Unlike automatic variables that can be initialized by either constants or expressions using both constants and previously initialized variables, static variables can only be initialized using constants or constant expressions.
