Thread: calculating monthly bank fees

hi everyone! i almost have my program finished (pretty surprised i actually do lol) but i'm having a couple problems. this is what the program should do (copied straight out of the textbook)

a bank charges $10 per month plus the following check fees for a commercial checking account:

$.10 for less than 20 checks
$.08 each for 20-39 checks
$.06 each for 40-59 checks
$.04 each for 60 or more checks.

the bank also charges an extra $15 if the balance of the account falls below $400 (before any check fees are applied.) write a program that asks for the the beginning balance and the number of checks written. compute and display the bank's service fees for the month.

input validation: do not accept a negative value for the number of checks written. if a negative value is given for the beginning balance, display an urgent message indicating the account is over drawn.


i'm having a problem with adding the initial $15 if the balance is under $400 and displaying the message if the balance is negative.

here is the code i have for this part of the program:

Code:

 // Calculate bank fees based on amount of checks user inputs. 

  // if (balance <= 400)

  //   fee = 15 + (

  if (checks < 20)

     fee = checks * .10;

  else if (checks < 39)

     fee = checks * .08;

  else if (checks < 59)

     fee = checks * .06;

  else if (checks >= 60)

     fee = checks * .04;

  else if (checks <= 0) 

  {

     cout << "Your account is overdrawn! \n";

     cout << "Number of checks must be zero or more. \n";

  }

the first three lines are commented out because i know they're wrong from trying to run the program. could anyone help me out by giving me some possible suggestions?? thank you

do i have add 15 to the fee to the line below // if (balance <= 400) or else if (checks <= 0)?? i'm sorry if this is a dumb question but it's these little problems that really confuse me.
