c++ - What happens to a dynamic array (on the heap) within a struct on the stack? -

-

my concern whether or not array should deallocated. here example:

typedef struct {     int *values;     int length; } a_struct;  void foo() {     a_struct mystruct;     mystruct.values = new int[num];        delete[] mystruct.values; // needed?     return;   }

my understanding mystruct (which on stack) deleted automatically upon "return" statement. delete "values" well?

it deallocate the pointer values, not points to - after all, a_struct know assigned pointer? maybe it's pointer stuff allocated on stack, or array shared struct.

so, yes, need manually deallocate (although in modern c++ "smart pointers" used manage memory).
