Need ideas for producing a program in c++ to do the following
1. Telephone numbers have to be entered into prog and validated as National Call, Local Call or Overseas Call.
2. Add money/credit.
3. As phone is connecting a message has do be displayed saying " please wait until we try and connect you" when connected "you are now connected to (number) please start your conversation" has to be displayed.
4. Also a timer to countdown total money/credit,which has been input by the user, when it reaches zero a message is displayed saying
"no credit left your call is disconnected".
Its kinda like a telephone box!
Any ideas would be greatly appreciated.
