. The electric company charges according to the following rate schedule: 9 cents per kilowatt-hour (kwh) for the first 300 kwh 8 cents per kwh for the next 300 kwh (up to 600 kwh) 6 cents per kwh for the next 400 kwh (up to 1,000 kwh) 5 cents per kwh for all electricity used over 1,000 kwh Write a function to compute the total charge for each customer. Write a main function to call the charge calculation function using the following data: Customer Number Kilowatt-hours Used 123 725 205 115 464 600 596 327 … … The program should print a three column chart listing the customer number, the kilowatt hours used, and the charge for each customer. The program should also compute and print the number of customers, the total kilowatt hours used, and the total charges.

here, hope it helps.

Explanation:

#include<iostream>

using namespace std;

int calculate(int N)

{

int rate=0;

for(int count=1;count<N;count++)

{

if(count<=300)

rate=rate+9;

else if(count<=600)

rate=rate+8;

else if(count<=1000)

rate=rate+6;

else

rate=rate+5;

}

return rate;

}

void main()

{

int costumer[20];

int wats[20];

int rates[20];

int i=0;

cout<<"please enter the information for the costomers below 0 to stop"<<endl;

while (costumer[i-1]!= 0)

{

cout<<"please enter the number of the coustomer "<<endl;

cin>>costumer[i];

if(costumer[i]==0)

break;

cout<<"please enter Kilowatt-hours used for the costumer "<<endl;

cin>>wats[i];

i++;

}

for(int j=0;j<i;j++)

rates[j]=calculate(wats[j]);

for(int j=0;j<i;j++)

{

cout<<" Customer Number Kilowatt-hours used charge"<<endl;

cout<<" "<<costumer[j]<<" "<<wats[j]<<" "<<rates[j]<<endl;

}

}
