Putting It All Together

Putting It All Together

Time to combine everything you have learned: data sections, registers, arithmetic, control flow, functions, and string operations.

Your Task

Write a program that computes the factorial of 5 (5! = 120) and prints the result followed by a newline.

Since 120 is a multi-digit number, you will need to convert it to a string of ASCII digits. The algorithm:

1. Compute 5! = 120 using a loop or function
2. Convert 120 to the string "120" by repeatedly dividing by 10:
   • 120 / 10 = 12, remainder 0 -> digit '0'
   • 12 / 10 = 1, remainder 2 -> digit '2'
   • 1 / 10 = 0, remainder 1 -> digit '1'
3. The digits come out in reverse order, so store them on the stack and print in the right order

Hints

• Use div with divisor 10 to extract digits
• Remember to xor rdx, rdx before each div
• Push each digit onto the stack as you extract it
• Count how many digits you pushed
• Print them all at once, or one at a time

Print: "120\n"
