We made the scanf demo this day.

Active Learning:

.section .text
.globl _start

a_function:
	push %ebp
	mov %esp, %ebp
	sub $8, %esp
	movl $100, (%esp)
	movl $20, 4(%esp)
	push $52
	// Draw the stack here
	// Note:  The program will actually crash after this

_start:
	mov %esp, %ebp
	push $82
	call a_function

	int $0x80
