$1$ Debugging a function $(4$ marks$)$

What this question is checking? Recently in class you have been introduced to programming

in general, and Matlab in particular. Programming requires a number of minor skills seldom taught

in lower level courses, such as interpreting errors, seeking tools and building flows. This question is

designed to test your understanding of these skills, and give you a chance to practice them.

a$)$ The doctor has prescribed your grandmother a vitamin tablet once every two days and iron

tablets once every five days in August.

Your brother wrote a M M TLAB function called 'TabletHelper' to help remind your grand$-$

mother which tablets to take on a given day. The program should print the date for each day

of the month. If the date is a multiple of $2,$ next to the date it should also print "Vitamins".

If the date is a multiple of $5,$ next to the date it should print "Iron". If the date is a multiple

of both $2$ and $5,$ next to the date it should print "Vitamins and Iron".

The program is shown below.function TabletHelper

for i$=1$:$31$ disp$($num$2$str$($i$),$'Vitamins'$)$ disp$($num$2$str$($i$),$'Iron'$)$ disp$($num$2$str$($i$),$'Vitamins and Iron'$)$ disp$($num$2$str$($i$))$endThis code has mistakes! Find all of the mistakes in your brother's code, explain why each

is incorrect, and suggest fixes for each mistake. Also submit the final correct version of the

function.

$($Note: We do not want you to write a new function that will work correctly. $$ key skill in

programming is being able to fix errors, not just start from scratch each time!$)$
