Error codes.

[pvellake]

This is what I'm trying to do:

Your new cell bill program must use 3 functions with parameters, as follows:

function calcRegBill – accepts one integer argument for the number of minutes used. Determines and returns the total amount due.
function calcPremBill – accepts two integer arguments, for the number of day minutes and number of night minutes used. Determines and returns the total amount due.
function printBill – accepts 4 arguments: a string account number, a character service code, an integer total number of minutes used, and an amount due. Note that this is a generic print bill function, which prints either a regular or premium bill.

This is what I have so far:

Please edit your post and use [code]code tags[/code] for all of your code - http://www.cplusplus.com/articles/jEywvCM9/

Your problem, most likely, lies in statements that resemble this (You do it several times throughout your code):

total = (25 + (b * .05)) << endl;

You're appending the stream insertion operator, complete with endline, to an assignment statement. My guess is that you had done some find/replace that went haywire. However, if you purposefully typed the aforementioned statement, you'll be dismayed to know that you cannot insert stream data into an arithmetic expression and assign the result to a variable.

Kindest regards.

Note: I didn't understand your formulas to calculate the bill. Why did you have to deduct minutes (line 38, 49, and 54). They could result in negative numbers.

I didn't do input validations after user enters values. Input validation is strongly recommended in order to run the program, smoothly and bug-free.

Anyway, This is how I would do [Keeping the formulas same as yours, except the above mentioned deduction parts]

Happy coding...
