c++ - Initializing an Array using Size of Operator? -


i have array initialize 

char arr[sizeof(int)];

would expression evaluate compile time constant or result in function call?

char arr[sizeof(int)];

as far language concerned, fine, though array declared (and defined), not initialized if local variable. if declared @ namespace level, statically zero-initialized.

note sizeof(int) constant expression of size_t type; value known @ compile time.
