How many objects of a given class can there be in a program?
It depends on the size of the object and the amount of (virtual) memory available. However, the size of an object is not determined by the amount of memory it physically occupies, but by the amount of memory it consumes. For example, a resource handle object occupies at least one word of memory, but the resource it refers to consumes additional memory. The sizeof operator only returns the size of memory occupied by the object itself, not the total memory consumed by the object.
