What is stack overflow? Which stack operation can potentially cause stack overflow?

What are the main uses of the stack?

In Section 5.4.1 on page 123, we discussed two ways of exchanging value1 and

value2. Both methods require eight memory accesses. Can you write a code fragment

that does this exchange using only six memory accesses? Make sure that your code does

not alter the contents of any registers. Hint: Use the xchg instruction.
