Learn subroutine, stack. stack frames, ESP, EBP, EIP, and input and output processing. Write an assembly program to calculate the factorial of an unsigned integer n (n!) You need to prompt the user to enter an unsigned integer: Enter unsigned integer (n!): To do this, use WriteString and ReadDec (see assignment6. question3 for a similar example) Pass the entered number to the Factorial subroutine The calculated n! needs to be displayed on console screen from main subroutine See the book page 305-306 where you will find main and factorial subroutines. Make the required changes and run the program Use Step Into instead of Step over to keep track of the stack, ESP, EBP, EIP during debugging To access the stack memory, copy the value of ESP from the register window and past it in the search text box in the memory window. Remember to have 0x (it tells debugger that the number is a hexadecimal number) in front of the pasted ESP value (0x4000407C). Submit the following: Last name 1.asm What will happen to the Factorial program's output when you try to calculate 13! and why? How many bytes of stack space will be used by the Factorial subroutine when calculating 3
