Question

You must write the code in 80x86 assembly language and must attach a screenshot of the output.

#

Pennies for Pay

Write a program that calculates how much a person earns in a month if the salary is one penny the first day, two pennies the second day, four pennies the third day, and so on with the daily pay doubling each day the employee works. The program should ask the user for the number of days the employee worked during the month, validate that it is between 1 and 31, and then display a table showing how much the salary was for each day worked, as well as the total pay earned for the month. The output should be displayed in pennies points, not in pennies.

Weight Loss

If moderately active persons cut their calorie intake by 500 calories a day, they can typically lose about 4 pounds a month. Write a program that has the users enter their starting weight and then creates and displays a table showing what their expected weight will be at the end of each month for the next 6 months if they stay on this diet.

Calories Burned

Running on a particular treadmill, you burn 4 calories per minute. Write a program that uses a loop to display the number of calories burned after 5, 10, 15, 20, 25, and 30 minutes.

Pic of output shown below:

For second question below is the assembly code:

push    rbp

        mov     rbp, rsp

        sub     rsp, 16

        mov     DWORD PTR [rbp-4], 1

        mov     esi, OFFSET FLAT:.LC0

        mov     edi, OFFSET FLAT:_ZSt4cout

        call    std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> > (std::basic_ostream<char, std::char_traits<char> >&, char const*)

.L3:

        cmp     DWORD PTR [rbp-4], 6

        jg      .L2

        mov     eax, DWORD PTR [rbp-4]

        mov     esi, eax

        mov     edi, OFFSET FLAT:_ZSt4cout
