An
electricity board charges the following rates to users
- For
first 100 units : 40p per unit
- For
next 200 units : 50p per unit
- Beyond
300 units : 60p per unit
All
users are charged a minimum of Rs.150. If the total cost is more than Rs.250.00 then
an additional
charges of 15% are added.Write a C++ program
using class to read the name of users & number of units consumed &
print out the charges with names.(Use Array of Objects)
