In this discussion board we are given a problem that is the billing department for the bank has asked for your team’s help. They want to develop a program that will determine the monthly charges for checking accounts. The following criteria are to be used:
Balance > = 100.00 will not be charged fees
Balance < 100.00 will be charged $9.95 monthly fee The first thing I would do is look at different steps to us to get to the desired answer. After I have figured them out I would write them in order. These steps I am writing down are called an algorithm. Now I had to pick the best algorithm style to use there are three While loop, Do while loop and For loop. I picked For loop due to this is going to be done for 12 months which gives me a set amount.
The algorithm in pseudo code steps are START INITIALIZE CONTROL VARIABLE (Checking account Balance) LOGICAL PROCESS (CHECKING BALANCE GREATER > = TO 100) TRUE (DO NOTHING) FALSE (MINUS 9.95 FROM CHECKING ACCOUNT) PRINT NEW BALANCE (YOU ONLY SEE THIS FOR FALSE STATEMENTS) END The flowchart for this discussion we are still using a For flowchart. To do this I first need to identify the symbols I will us. In flowcharts there are a variety of symbols that are used with various operations. The first symbol I used is the one that means start and end.

The second symbol I would used is for decision making
The third symbol would be processing this block has only one way in and one way out

The fourth symbol is the print of you output

The last symbol we need to worry about is flow lines which are very important to how the chart will work.

This is the flowchart with all the symbols put in the order of the algorithm. I show what the symbols look like because this is important to having a flowchart that can be read by other students. The two work together to builds a picture that you now see. You will need this when you go further into programming of computers the order and naming is important.
