I am trying to iterate through all of the days of the week so that the input statement asks for 'Did the employee work on Monday of week 1' and then Tuesday and then Wednesday etc but sprintf and fprintf both dont work. Is there a funciton that allows you to put cells in a statement like that?
days = 'Monday Tuesday Wednesday Thursday Friday Saturday Sunday';
days = split(days);
for weeknum = 1:2
for daynum = 1:7
letter = input(sprintf('Did the employee work on %d of week %d (y/n): ',days(daynum),weeknum),'s');

You were quite close, but you missed an indexing and got a format wrong
days = 'Monday Tuesday Wednesday Thursday Friday Saturday Sunday';
days = split(days);
for weeknum = 1:2
for daynum = 1:7
letter = input(sprintf('Did the employee work on %s of week %d (y/n): ', days{daynum}, weeknum),'s');
%stuff
end
end
But I would suggest
days = ["Monday" "Tuesday" "Wednesday" "Thursday" "Friday" "Saturday" "Sunday"];
for weeknum = 1:2
for daynum = 1:length(days)
prompt = "Did the employee work on " + days(daynum) + " of week " + weeknum + " (y/n): ";
letter = input(prompt, 's');
%stuff
end
end

Ran in:
fprintf("You should use %%d to print integer values like: %d\n", 3)
You should use %d to print integer values like: 3
fprintf("You should use %%s to print text like: %s\n", "hello")
You should use %s to print text like: hello
fprintf("Using %%s to print integer values may not do what you expect: %s\n", 65)
Using %s to print integer values may not do what you expect: A
fprintf("Using %%d to print text data also may not do what you expect: %d\n", 'hello')
Using %d to print text data also may not do what you expect: 104 Using %d to print text data also may not do what you expect: 101 Using %d to print text data also may not do what you expect: 108 Using %d to print text data also may not do what you expect: 108 Using %d to print text data also may not do what you expect: 111
char(65)
ans = 'A'
double('hello')
ans = 1×5
104 101 108 108 111
