I think my answer is not correct for this question, anyone can help me to check it? Thanks

Attached file is the question. Here is my code

    B = 10000;
    m = 0;
    P = input('monthly payment?')
    while B>0
        B=B*(1.005);
        B=B-P
        m=m+1
    end

Hi,

It matches with your flowchart, Why do you thing it is not correct?

[Erwin Koman]

I think the answer should be one answer only not repeatedly.

Erwin,

You're using a while loop, of course you are iterating and you will have multiple stages (you may not wanna call them answer).

Maybe what you're looking for is the final value of m and B. if so then you have to supress them from being showed in MATLAB command windows by terminating them with ;

B = 10000;
  m = 0;
  P = input('monthly payment?')
  while B>0
      B=B*(1.005);
      B=B-P;
      m=m+1;
  end
B
m

And just view them after the while loop is finished.

Okay, I get it. Thanks.

Good, then would you please accept the answer.

    B = 10000;
    m = 0;
    P = input('monthly payment?')
    while B>0
        B=B*(1.005);
        B=B-P;  %changed
        m=m+1;  %changed
    end
    disp(m);    %changed

Thank you.
