Assume that two values need to be swapped, such as is done in a number of commonly used Computer Science sorting algorithms. The typical high-level code is as follows: temp - num1; num1 = num2; num2 - temp: This could be implemented on a line-by-line basis in assembly language using registers, but that would require two instructions for reach line of code as follows: mov eax,num1 mov temp, eax mov eax, num2 mov numi, eax mov eax, temp mov num2, eax Understandably, the above seems inefficient. Instead of using registers and mov instructions, another possibility is to use the stack. Not only is a runtime stack a way to save and restore values, it can also be useful in swapping two values. Another method of swapping two values is to use the exchange instruction. However, for this lab you will use the push and pop instructions to swap two values.

Question
The class I'm taking is assembly
I am completely stuck. Can you please write out program so I can successfully run and compile program in visual studio. I have attached the instructions . i have also attached my work i have done so far. can you please tell me where i went wrong. Please view both attachments before answering. Thank you so much for your help!
Transcribed Image Text:In this lab task you will use the PUSH and POP instructions to manage the transfer of data to
and from the runtime stack.
Write a program that uses only PUSH and POP instructions to exchange the values in the
EAX and EBX registers.
Testing Specification
Store values into the EAX and EBX registers. Compile and run your program to validate that
your program sequence of statements exchanges the original register values.
Documentation Requirements
Be sure to provide a commented out header that describes your program. Include in your
header description the compiler that you used. Provide inline comments to document your
solution.
Background Discussion
Assume that two values need to be swapped, such as is done in a number of commonly used
Computer Science sorting algorithms. The typical high-level code is as follows:
temp - num1:
num1 - num2;
num2 = temp:
This could be implemented on a line-by-line basis in assembly language using registers, but
that would require two instructions for reach line of code as follows:
mov eax, num1
mov temp, eax
mov eax, num2
mov num1, eax
mov eax, temp
mov num2, eax
Understandably, the above seems inefficient. Instead of using registers and mov
instructions, another possibility is to use the stack. Not only is a runtime stack a way to save
and restore values, it can also be useful in swapping two values.
Another method of swapping two values is to use the exchange instruction. However, for
this lab you will use the push and pop instructions to swap two values.
