Start by getting the files. Type $264$get hw$05$ and then cd hw$05$ from bash.

You will find only one file: mintf.h$.$ That is the header file. It defines the signature of two of the functions you will implement: mintf$(...)$ and print$\_$integer$(...).$

You will be creating three new files: mintf.c$,$ test$\_$mintf.c$,$ and test$\_$mintf.txt$.$ There is no starter code $($other than the header file$).$

mintf.c is where your mintf$(...)$ and print$\_$integer$(...)$ implementations will go$.$ Copy your print$\_$integer$(...)$ from HW$02$ into it$.$ Copy the function signature for mintf$(...)$ from mintf.h into mintf.c$.$ Make sure all of the following headers are included at the top of your mintf.c$.($Type these manually into your file.$)$

#include

#include

#include

#include "mintf.h$"$

test$\_$mintf.c will contain a main$(...)$ function that will test your mintf$(...)$ and print$\_$integer$(...).$ It must exercise all of the functionality in those two functions. For this homework, that means that in the course of running your test$\_$mintf.c file, every line of code in your mintf.c should be executed at some point. To do this, you simply have several mintf$(...)$ that include all of the format codes above, including a variety of valid values, including positive integers, negative integers, $0,$ strings, and an empty string. It should also have a few print$\_$integer$(...)$ statements to test that on its own. This will give you a very simple way to know for sure if your code works.

Use test$-$driven development to do this assignment incrementally.

test$\_$mintf.txt will contain the expected output from running your tests in test$\_$mintf.c$.$ It will be a simple text file.

To test if your code works perfectly, you will run the following:

gcc test$\_$mintf.c mintf.c $-$o test$\_$mintf # compile your test together with your mintf.c to create an executable called test$\_$mintf

$./$test$\_$mintf $>$ test$\_$mintf.actual # run your executable and send the output to a file called test$\_$mintf.actual $($That filename is arbitrary.$)$

diff test$\_$mintf.actual test$\_$mintf.txt # compare the actual output with the expected output using the diff command

The diff command prints the differences so if you see any output at all, then your test failed. If you see no output, then it passed.

gcc test$\_$mintf.c mintf.c $-$o test$\_$mintf && $./$test$\_$mintf $|$ diff test$\_$mintf.txt $-$
