Answer:
Microsoft Windows - More susceptible to viruses
Linux - Limited support system
Apple - Fewer compatible applications
Explanation:
Generally windows is more susceptible to viruses.
Linux is open source meaning it's up to the community to help you.
Apple has been supporting more applications in these coming years but it still lacks the wide range of apps windows supports.
This program multiplies integer inputs A and B, by repeatedly adding B to RESULT while decrementing A.
It will work fine when either A or B is zero. If A is zero, it will branch to QUIT immediately. If B is zero, zero will be added repeatedly to the result (which also is initialized with zero).
LOOP, RESULT etc. are called labels. They translate into a memory address location of a variable or machine instruction. But it is much more readable to have them as english words while creating your program. Also, they make your program relocatable, in the sense that while writing, you don't have to decide on which physical address your program will run.
