Applying potential difference to a conductor, by potential force, free electrons gain energy and move from low to high potential. Thus, electrons move from one atom to another.

It has positive and negative charges, which is expressed in coulomb. An electrical phenomenon is caused by flow of free electrons from one atom to another.

I'm assuming hardware.

Remember, Hard = Physical.

If that's not it, try peripherals.

Look at the logic program below. Set a breakpoint after each commented instruction. You can also single step through the program

Goshia [24]

Using programming knowledge, it is possible to use programming logic, we can differentiate and find the terms

<h3>Writing the code and understanding the programming logic:</h3>

.data

sourceword:

.word 0xAB

wordmask:

.word 0xCF

operand:

.long 0xAA

.text

.globl _start

_start:

movw sourceword, %ax # ax=0x00AB ( move the word value of sourceword =0x00AB to ax register.)

movw %ax, %bx # bx=0x00AB ( copy the value of ax to bx register.)

xorw %cx, %cx # cx=0000 ( cx=cx XOR cx, that is clear cx register.)

andw wordmask, %ax # ax=0x008B ( ax=ax AND wordmask= 0x00AB AND 0x00CF= 0x008B)

orw wordmask, %bx # bx=0x00EF (bx=bx OR wordmask= 0x00AB OR 0x00CF= 0x00EF.)

xorw wordmask, %cx # cx=0x00CF (cx=cx XOR wordmask= 0x0000 XOR 0x00CF=0x00CF.)

movl operand, %eax # eax=0x000000AA. ( copy the 32-bit value of operand=0x000000AA to eax.)

movl %eax, %ebx # ebx=0x000000AA.( copy the value of eax to ebx.)

movl %eax, %ecx # ecx=0x000000AA. ( copy the value of eax to ecx.)

shll $3,%eax # eax=0x00000550. ( logical shift left of eax=0x000000AA by 3 bits.)

Answer:

Following are the program in the Python Programming Language.

#set the infinite while loop

while(True):

#get string input from the user

name=input()

#get integer input from the user

num=int(input())

#set the if statement to break the loop

if(num==0):

break

#otherwise, print the following output

else:

print("Eating {} {} a day keeps the doctor away.".format(num, name))

Output:

oranges

Eating 5 oranges a day keeps the doctor away.

apple

Explanation:

Following are the description of the program:

Set the loop that iterates at infinite times and inside the loop.
Declare two variables which are 'name' that get string type input from the user and 'num' that get integer type input from the user.
Set the if conditional statement for break the infinite while loop.
Otherwise, it prints the following output.
