To perform an add operation on a stack machine, the following steps are taken: two pops, an add and another pop.
True
False
These are the only instances that can prevent an add operation on a stack machine from completing successfully: either of the two pops result in an underflow, or the addition is out of range.
True
False
The calculator uses a stack for arithmetic operations. During an add operation, if the result is beyond the range of representable values, the stack pointer needs to be incremented twice to return the stack to the condition it was in before the add was attempted.
True
False
To display a number on the monitor, it needs to be converted from an ASCII string to a two's complement integer.
True
False
The OpNeg subroutine forms the 2's complement negative value of the top value on the stack. It is accomplished by the following sequence of operations: pop the top of the stack, perform the bitwise NOT of this value, add the value 1, push the result on the stack.
True
False
The "peek" subroutine returns the value of the topmost element of the stack without changing the stack. Thus, the only error checking we need to do is to check for overflow.
True
False
. A stack machine performs the following sequence of operations. What is the final result popped:
71
128
31
24
A peek subroutine is defined as one that returns the value of the top of the stack without removing the element from the stack. After the following sequence of operations, what result is last popped off the stack?
5
3
9
4
A stack machine performs the following operations. The result after the pop is push 7 push 3 multiply push 4 push 3 add multiply pop
147
84
17
21
A peek subroutine is defined as one that returns the value of the top of the stack without removing the element from the stack. After the following sequence of operations, what result is last popped off the stack? push 5 push 3 push 9 peek push 4 pop peek pop
