Question

What can happen when a buffer of an unknown size is copied over into a limited-sized stack buffer?

a.

The copy operation will cause anything residing after the buffer in the stack to be overwritten with whatever is sent as input

b.

The copy operation will dynamically allocate more space in the stack for the incoming data

c.

The copy operation will verify that the received data fits into the stack buffer before copying it

d.
