ELECTRICITY
BILL MANAGEMENT SYSTEM (C LANGUAGE)
1. Title
Electricity
Bill Calculation System in C Language (100 Units Free Scheme)
2.
Introduction
Electricity
billing systems are used to calculate the electricity charges consumed by a
customer.
This project is developed in C programming language to calculate the
electricity bill based on units consumed.
In this
system, the first 100 units are free as per government scheme, and
charges are applied only after 100 units.
This program
takes customer details and electricity units consumed as input and
calculates the final bill amount automatically.
3.
Objective
The
objectives of this project are:
- To calculate electricity bills
using C programming.
- To apply government scheme
(first 100 units free).
- To practice structures,
conditional statements and arithmetic operations in C.
- To generate a formatted
electricity bill.
4.
Features of the System
- Customer Name Input
- Consumer Number
- Units Consumed
- First 100 Units Free
- Automatic Bill Calculation
- Display Final Bill

Algorithm
1.
Start the program.
2.
Input customer name.
3.
Input consumer number.
4.
Input units consumed.
5.
Check if units ≤ 100
o Bill = 0
6.
If units between 101 and 200
o Bill = (units −
100) × 5
7.
If units between 201 and 300
o Bill = (100 × 5)
+ (units − 200) × 7
8.
If units above 300
o Bill = (100 × 5)
+ (100 × 7) + (units − 300) × 10
9.
Display customer details and bill amount.
10.
Stop the program.
