How do I end a program when a condition is met using only if-else-elseif statements?

I’m making a program where I need to have the program stop asking questions if an invalid input is entered by the user. How would I do this using only if-elseif-else statements, not using commands like return or break?

Why are you limiting yourself? Is this homework? Using keywords like return and break will make code much more readable and compact.

Yes, sorry if that’s against the rules of the board. I just don’t understand the general concepts of nesting if-else statements and can’t seem to make it work.

Something like this will work (edit to add nesting):

function out=MyFunction(in)
if in<1
    if in==0.5
        %do something
    else
        %do something different
    end
elseif in==2
    %do something else
else
    %do nothing
end
%don't put code here
end

You could also use code at the beginning of your function to find out the type of code that should be run and then use that in a switch case structure.

Thank you so much I finally got it!
