Write a program that take 10 64-bit variables and adds them using the 64-bit gen

Question

Write a program that take 10 64-bit variables and adds them using the 64-bit general purpose registers to get a sum that is equal to0xffffffffffffffff. The sum itself should be a 64-bit value and should contain the hexadecimal value 0xffffffffffffffff after all 10 64-bit variables have been added to produce the sum.

Program Requirements

The 64-bit registers that can be used are rax, rbx, rcx, and rdx. These are the 64-bit versions of the 32-bit general purpose registers eax, ebx, ecx, and edx. A 64-bit variable is declared as a QWORD. All 64-bit variables for this program must have a length equal to a QWORD. The 10 variables may have only decimal or hexadecimal numeric values in them. The 10 variables are added much like the variables were for program 1 in that thevariables have their initial values hardcoded to whatever values you’d like to choose, as long as their sum adds up to 0xffffffffffffffff.

There must be a variable declared named sum in addition to the 10 variables that you must declare. You use the 64-bit registers to add the 10 variables to get 0xffffffffffffffff, and the variable sum must have the final value of the addition of all 10 variables assigned to it before the program ends.

Unlike previous 32-bit programs in the course, the 64-bit program does not need any directives for the processor type or the memory model. So there will be no .386, .586, or .model directives you need to supply.
