Calculate Electricity Bill Of Person using Class

Write a C++ Program To Calculate Electricity Bill Of Person using Class. Here’s a Simple Program To Calculate Electricity Bill Of Person using Class in C++ Programming Language.

Algorithm for Calculating Electricity Bill : :

• To Calculate Electricity Bill Of Person using Class,first we have to create and call  get( ) function to take input details of the customer.
• After get( ) , we create and call a new function i.e  calc_bill( ) to calculate the total bill of the customer on the behalf of units consumed by the customer .
• At last , we call the put( ) function to print or display customer or person electricity bill on the screen.

Here are some tarrifs set per unit consumption of electricity to the customer.

Unit tarrif  :

• 100 RS. 1.20 per unit
200 RS. 2 per unit
300 RS. 3 per unit

Here below is the Source code in C++ to Calculate Electricity Bill Of Person using Class.This code is succesfully compile and run(on Codeblocks) on the Windows System and produces the output below.

SOURCE CODE : :

```/* C++ Program to Calculate Electricity Bill Of Person using Class  */

#include<iostream>
using namespace std;

class e_bill
{
private:
int c_no;
char c_name[20];
int units;
double bill;
public:
void get()
{
cout<<"Enter Details of Customer Below :: \n" <<endl;
cout<<"Enter Customer No. :: ";
cin>>c_no;
cout<<"\nEnter Customer Name :: ";
cin>>c_name;
cout<<"\nEnter No. of Units used :: ";
cin>>units;
}

void put()
{
cout<<"\nEntered Details of Customer are :: " <<endl;
cout<<"\nCustomer No. is : "<<c_no;
cout<<"\n\nCustomer Name is : "<<c_name;
cout<<"\n\nNumber of Units Consumed : "<<units;
cout<<"\n\nBill of Customer : "<<bill;
}

void calc_bill()
{
if(units<=100)
bill=units*1.20;
else if(units<=300)
bill=100*1.20+(units-100)*2;
else
bill=100*1.20+200*2+(units-300)*3;
}
};

int main()
{
e_bill b1;
b1.get();
b1.calc_bill();
b1.put();

cout<<"\n";

return 0;
}```

OUTPUT : :

```/* C++ Program to Calculate Electricity Bill Of Person using Class  */

Enter Details of Customer Below ::

Enter Customer No. :: 123

Enter Customer Name :: CodezClub

Enter No. of Units used :: 2000

Entered Details of Customer are ::

Customer No. is : 123

Customer Name is : CodezClub

Number of Units Consumed : 2000

Bill of Customer : 5620

Process returned 0```
