I need to write a c++ program that will do the following:

Inputs:

(1) (from keyboard) File name: if the name is "NONE", read

data from keyboard. Otherwise, open the input file and

read data from the file.

(2) (from file OR keyboard) INPUT for a one utility customer,

in the format (one space before customer name):

format: PreviousReading CurrentReading CustomerName

sample: 04304450 04305150 Sam R. Jones

NOTES:

[1] Meter readings are 8-digit integers.

[2] Utility charges can be up to $9,999.99

[3] Customer name is a string that can contain spaces.

[4] When the end_reading < start_reading, program must:

a) output message:

BAD METER READINGS: xxxxxxxx (START) xxxxxxx (END)

b) do not attempt to calculate charges, but still

print the statement, including the following lines

for charges due and power usage.

CHARGES DUE: $DEFERRED

POWER USAGE: ????? KWH

Computation: Utility charges are based on the following scale:

Power (KWH)Used Utility Charge Formula

---------------- -------------------------------

0 - 500 $53.00 + 0.165 x KWH

501 - 1000 $75.50 + 0.125 x KWH

1001 - 3000 $125.75 + 0.117 x KWH

above 3000 $400.07 + 0.017 x KWH
