Hey everyone, this is the last part of my Homework and I'm stuck. We are supposed to ask the user to input number of years, then take budget as an input for each year and plot all of this on a bar graph with years X and budget Y. I can't even get my second input to work. Here is what I have so far -
clear;
clc;
clf;
years=input('How many years? ');
for curyear=1:years;
fprintf('Write budget amount for Year #%g: \n','curyear')
end
I'm open to any help. Thanks!

The second call to input() should probably be inside your loop over years, since you need to ask for a different amount for each year.

I think I am very close. Here is my new code, do you think this will work as I can not test it at the moment?
clear;
clc;
clf;
years=input('How many years? ');
for curyear=1:years;
fprintf('Write budget amount for Year #%g: ',curyear)
budget=input('');
bar(curyear,budget);
hold on
end

Why did you not put the prompt inside input like you did the first time?
userPrompt = sprintf('Write budget amount for Year #%g: ',curyear)
budget=input(userPrompt);

If you store your budget for each year you just need a single call of bar
years = input('How many years? ');
for curyear=1:years;
budget(curyear) = input(sprintf('Write budget amount for Year #%g: ',curyear));
end
bar(1:years,budget);
xlabel('Year')
ylabel('Budget')
