Write a function which takes one parameter int num, and prints out a countdown timer with minutes and seconds separated by a colon (:). It should print out one line for each second elapsed and then pause one second before printing out the next line. A few things to note:

- You can assume that calling the function usleep(1000000) makes the program pause for one second

- It should count down from num minutes:zero seconds to zero minutes:zero seconds

- Your function must have the following signature:

void timer(int num)

You do not need to demonstrate calling this function from main().

You don't need to format the output nicely; the below is acceptable output for calling this function when minutes is 10:

10:0

9:59

9:58

…

9:1

9:0

8:59

8:58

…

0:2

0:1

0:0

Write a subroutine that takes an int (.long) parameter and squares it. The parameter should be passed in on the stack. The answer should be returned in eax. The subroutine should not disturb any registers except eax, ecx, and edx. (Save any registers on the stack and restore them before exiting the subroutine.) Upon entry to the subroutine, push ebp, etc., to access the parameter.

Write a function pretty_print, which takes one parameter that can be any type of namedtuple. It "pretty prints" the contents of the namedtuple, including both the names of its fields and their values. This is subject to a few rules. Each field and its value are displayed on one line, with the name of the field appearing first, followed by a colon and a space, followed by the value of the field converted to a string. The fields should be...
