Question

I declared simple structure:

struct Heap {
  int size;
  int *heap_array;
};

When Im trying to create table, where k is int from stdin:

Heap *rooms = new Heap[k];

I got:

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted

Using int literally everything is ok:

Heap *rooms = new Heap[0];

How to declare such table?

Answer 1

Chances are your value read from stdin was invalid. If the read failed you might have some default value in it like 2^32.
