Question

An electricity board charges the following rates to domestic users to discourage large consumption of energy :For the first 100 units : 50 P per unit and Beyond 300 units : 60 P per unit, 100-300 units:55 pIf the total cost is more than Rs.250.00 then an additional surcharge of 15% is added on thedifference. Define a class Electricity in which the function Bill computes the cost

Answer 1

#include<iostream>
#include<conio.h>
using namespace std;
class Electricity

char name[30];
int unit;
float Amount;
public:
void Input()
{
cout<<"\nEnter the Name and Units of Electricity user: \n";
cin>>name>>unit;
}
void Bill()
{
if(unit<=100)
{
Amount=unit*0.40;
Amount=Amount+150;
}
else if(unit<=200||unit>100)
{
Amount=unit*0.50;
Amount=Amount+150;
}
else if(unit<=300||unit>200)
{
Amount=unit*0.60;
Amount=Amount+150;
}
}
void print()
{
if(Amount>=250)
{
Amount=Amount+0.15;
}
cout<<name<<"\t"<<Amount<<endl;
}
};
