Functions and Global Variables

This is my code. (Edited)

function B = PBTask4P2b_f(COUNTER)
B = input('TRUCK B: ');

while COUNTER < 1000
B = B + COUNTER;
if COUNTER > 1000
    COUNTER = 0;
    fprintf('Counter has been reset to 0.\n')
else
    fprintf('COUNTER = %f.\n',B);
end
end
end

This is the question. How can i do from the above codes ? I need to get the answers from the command window, not by running the program. Please note that i have already declared the variable COUNTER and initialized it to 0.

The assignment doesn't ask for the user to input data within either task function...

@dpb So, how am i supposed to get the data from ?

The example usage of your functions in the problem statement shows it being passed as an argument to the two functions, doesn't it?

Your way, there's no need for an argument variable.
