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)
