Using libraries with functions and procedures
Not what you're looking for?
As you were reviewing the different programming languages on the Internet, you found some libraries with functions and procedures that you could use rather than write the code from scratch on your own. However, some of the code needs some modification to fit into your program. Nevertheless, you find 3 sets of code that you can reuse and have an implementation of the code.
Here is my code. I don't know how to start
Program Name { //begin of program
Procedure TrackPayment {
if amount_received < billing_amount then
amount_owing = billing_amount - amount_received
if date_payment_received > thirty_days then
late_fee_amount = late_charge_rate * billing_amount
account_balance = account_balance + amount_owing + late_fee_amount
}
Procedure CalculateInvoice {
if client_type = regular then
billing_amount = regular_price
else
billing_amount = regular_price - (service_price * discount_rate)
billing_amount = billing_amount + account_balance
}
Procedure PrintInvoice {
print client_name
print client_mailing_address
print invoice_number
print invoice_date
print billing_date
print billing_amount
print billing_period
}
begin main ( ) {
do TrackPayment
do CalculateInvoice
do PrintInvoice
}
} //end of program
