Question.7
A developer uses a constexpr value as an array size:
constexpr
constexpr int NUM_SENSORS = 8; int readings[NUM_SENSORS]; // Array size from constexpr
Can a const (non-constexpr) variable be used as an array size in C++?
const
Select Answer
No -- only constexpr or literals can be array sizes in C++
Yes -- const int works as an array size in C++ (but not in C)
const int
Only with VLA (variable-length array) extension
Both A and B are wrong -- only #define works
#define
