Question

Why do stack variables always have a fixed size?

a.

Because the offsets generated by the compiler for accessing those variables are predetermined and hard-coded into the machine code

b.

Because programs frequently neglect to perform bounds checking on incoming data

c.

Because programs dynamically allocate stack space based on the amount of information passed

d.

Because programs verify that the received data fits into the stack buffer before copying it
