Hyde Park Electric Co. bills its customers on the basis of kilowatt hours (KWH) used, as follows:

Kilowatt hours (KWH) used​​​Rate

1-100 7 cent per KWH

101-250 RM7.00 + 5 cents * KWH over 100

251-750 RM14.50 + 4 cents * KWH over 250

Over 750​​​​​RM34.50 + 3 cents * KWH over 750

The input will include each customer’s name, Account number and the number of kilowatt hours used (must be a positive value). The output should display the following for each customer: Name, Account number, kilowatt hours used and amount of the bill. *The program should be repeated if the user input is ‘Y’ or ‘y’.

Sample Output Display after the calculation:

Customer Name​​: Kate Loo

Account Number ​​: 12098765

KWH Used​​​: 320

​

Total Bill​​​: RM 17.3

Do you wish to continue​: Y

***Calculate the next customer bill if the user input is ‘Y’.

Answer 1

#include <iostream>

using namespace std;

float calcuate(float KWH)

{

float bill=0;

int diff;

  

if(KWH>0 && KWH<101)

{

bill=(7*KWH)/100;

}

else if(KWH>100 && KWH<251)

{

bill=7+(5*(KWH-100)/100);

}

else if(KWH>250 && KWH<751)

{

bill=14.50+((4*(KWH-250))/100);

}

else if(KWH>750)

{

bill=34.50+((3*((KWH-750)))/100);

}

return bill;

}
