There are several important uses of runtime stacks in programs (select all that apply):
when the call instruction executes, the cpu saves the current subroutine return address on the stack.
a stack makes a convenient temporary save area for registers when they are used for more than one purpose.
after they are modified, they can be restored to their original values.
when calling a subroutine, you pass input values called arguments by pushing them on the stack.
the stack provides temporary storage for local variables inside subroutine

There is a simple pattern for determining if a binary number is odd. what is it and why does this pattern occur? how many bits would you need if you wanted to have the ability to count up to 1000? how high could you count in binary if you used all 10 of your fingers as bits? (finger up means 1, finger down means 0)

What is the first step in creating a maintenance ?

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
