Write a pic16f877a assembler subroutine called “mul_8x8” to multiply register numb1 in memory location 20h, with register numb2 in memory location 21h. the least significant byte result must be placed in register “answl” in memory location 22h. the most significant byte result must be placed in register “answh” in memory location 23h. data in registers numb1 and numb2 must remain unchanged after the multiplication. first sketch a flowchart to determine the program structure and then write the firmware source code. put flow chart also in answer

Iwould try the first option, first then if that didn't work i would try the last option.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !

Idon't see any answer choices for your question, but the answer would to highlight the box, and drag the box to the box of choice (or do a simple copy and paste, and delete the old data).
