back again sorry but need help starting problem

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

$.10 each for less than 20 checks
$.08 each for 20-39 cecks
$.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 beginning balance and the number of checks written. Compare 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 overdrawn.

her is what i have so far, if you don't mind could you tell me the operations i need to figure this out:
C++ Syntax (Toggle Plain Text) 
  1. #include <iomanip>
  2. #include <iostream>
  3. using namespace std;
  4.  
  5. int main()
  6. {
  7. 	double begbal, checkw, ppch, banksf;
  8. 	banksf = 10
  9. 	cout << "Enter your beginning balance ";
  10. 	cin >> begbal;
  11. 	cout << "Enter the number of written checks ";
  12. 	cin >> checkw
  13.  
  14. 	if (checkw < 20)
  15. 		ppch = .10
  16. 	else if (checkw == 20 || checkw <= 39)
  17. 			ppch = .08
  18. 	else if (checkw == 40 || checkw <= 59)
  19. 			ppch = .06
  20. 	else if (checkw > 60)
  21. 			ppch = .04
  22. 	else
  23. 		cout << fixed << setprecision(2);
  24.  
  25. 	return 0;
  26. }

Use a while or a do while condition to neglect negative input.

You can save writing, and unnecessary testing in your check charge section:
c++ Syntax (Toggle Plain Text) 
  1.         if (checkw < 20)
  2. 		ppch = .10
  3. 	else if (checkw == 20 || checkw <= 39)
  4. 	         ppch = .08
  5. 	else if (checkw == 40 || checkw <= 59)
  6. 		ppch = .06
  7. 	else if (checkw > 60)
  8. 		ppch = .04
  9. 	else
  10. 		cout << fixed << setprecision(2);
lines 3 and 5 don't need to check for equality to the low end, the fact the previous test was false ensures that.
Line 7 can simply be an else - you know the number of checks is 60 or more by the time you get here.
Why do you have the formatting statement as part of this if...else block? It should stand alone.
Revision:
C++ Syntax (Toggle Plain Text) 
  1.         if (checkw < 20)
  2. 		ppch = .10
  3. 	else if ( checkw <= 39)
  4. 		ppch = .08
  5. 	else if ( checkw <= 59)
  6. 		ppch = .06
  7. 	else 
  8. 		ppch = .04
  9.  
  10. 	cout << fixed << setprecision(2); //should be moved elsewhere in code
From here, you need to test the balance to determine if penalty applies, then deduct fees from balance.

Of course, in between lines 11 and 13 of your original post, you must check for negative balance, display the message required. It's not clear whether you then exit the program, or let the user try again.
Everyone's gotta believe in something. I believe I'll have another drink.

C++ Syntax (Toggle Plain Text) 
  1. //Chpt4prgm11
  2. //Micah Standing
  3.  
  4. #include <iomanip>
  5. #include <iostream>
  6. using namespace std;
  7.  
  8. int main()
  9. {
  10. 	double begbal, checkw, ppch, bankaf, extrabf;
  11. 	bankaf = 10
  12. 	extrabf = 15
  13. 	cout << "Enter your beginning balance ";
  14. 	cin >> begbal;
  15. 	cout << "Enter the number of written checks ":
  16. 	cin << checkw
  17.  
  18.  
  19.  
  20.                 cout << fixed << setprecision(2);
  21. 	if (checkw < 20)
  22. 			ppch = .10
  23. 	else if ( checkw <=39)
  24. 			ppch = .08
  25. 	else if (checkw <=59)
  26. 			ppch = .06
  27. 	else
  28. 			ppch = .04
im not understanding, where does the equations for the negatice balance and what u mean when u say i need to test the balance, then deduct fees and also is the setpercision command in the right place, also does that extrabf thing ok its for the extra $15 if it's below $400.

Why did you start a new thread? You should have just added to your existing thread so that people would know what in the world you are talking about.
Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

use nested if...check first if checkw is less than zero to avoid the negative input...u can modify it to re-request for an input or to quit

don't forget to put semicolons after statements
anyway,

for the additional $15 if balance is < $400

c++ Syntax (Toggle Plain Text) 
  1. if (begbal<400)
  2. total_bank_fees += 15;

equation for check fees:
c++ Syntax (Toggle Plain Text) 
  1. total_check_fees = ppch * checkw;

then just add everything
c++ Syntax (Toggle Plain Text) 
  1. total_bank_fees += total_check_fees;


use do while for the validation of balance
c++ Syntax (Toggle Plain Text) 
  1. do {
  2. cin>>begbal;
  3. if (begbal<0)
  4. cout<<"Your account is overdrawn.";
  5. }while (begbal<0);

then do the same with checks
