Project Concepts & Logic
The core logic relies on classifying consumers into 'Domestic' or 'Commercial' categories.
Key Concepts:
• Structures (struct): Used to aggregate mixed data types (ID, Name, Readings) for each consumer.
• Conditional Logic: Distinct slab rates applied based on connection type.
• Tiered Pricing: Rate per unit increases as consumption bands increase (e.g., 0-100 units vs >200 units).

Algorithm: Initialization & Input
- Start: Initialize program and define 'struct Bill'.
- Setup: Set consumer count to 5.
- Loop: Iterate through each consumer.
- Input: Read Name, ID, Meter No, Previous & Current Readings.
- Configuration: Read connection type (Domestic/Commercial).
4
Algorithm: Calculation & Output
- Compute Units: Current Reading - Previous Reading.
- Check Type: If Domestic, apply lower slab rates; else apply Commercial rates.
- Apply Charges: Add fixed charges and tax percentage to base amount.
- Repeat: Continue loop for all consumers.
- Display: Print final bill report for all users.

Flowchart Structure
The logical flow of the system:
1. Input Phase:
Read Customer Name, Connection Type (Domestic/Commercial), and Units Consumed.
2. Processing:
Calculate base bill using the tiered slab rates defined in the code.
3. Surcharge Application:
If the total bill exceeds Rs. 500, apply a 5% extra surcharge.
4. Output:
Display final bill amount with details.

Code: Data Structure Definition
The foundational setup includes library imports and the structure definition:
#include <stdio.h>
#include <string.h>
struct Bill {
char name[30];
char type[15]; // "domestic" or "commercial"
int units;
float amount;
};
7
Code: Calculation Logic
The calculation logic handles different rates for domestic and commercial users:
float calculateBill(int units, char type[]) {
float bill = 0.0;
if (strcmp(type, "domestic") == 0) {
if (units <= 100) bill = units * 1.50;
else if (units <= 200) bill = 150 + (units - 100) * 3.00;
else bill = 150 + 300 + (units - 200) * 5.00;
} else { // Commercial Rates
if (units <= 100) bill = units * 4.00;
else if (units <= 200) bill = 400 + (units - 100) * 6.00;
else bill = 400 + 600 + (units - 200) * 8.00;
}
return bill;
}

Code: Main Execution
The main function coordinates input, processing, and output:
int main() {
struct Bill b;
printf("Enter Name, Type (domestic/commercial), Units: ");
scanf("%s %s %d", b.name, b.type, &b.units);
// Calculate Bill
b.amount = calculateBill(b.units, b.type);
// Apply Surcharge if Bill > 500
if (b.amount > 500) {
b.amount += b.amount * 0.05; // 5% Surcharge
}
printf("\nCustomer: %s\nTotal Bill Amount: Rs. %.2f\n", b.name, b.amount);
return 0;
}

Output Analysis: Bill Comparison
Comparison of final electricity bills for 5 consumers. Commercial users (Mahesh, Kavya) show significantly higher bills due to higher slab rates and consumption.
Key Data Points:
- Ramesh (Domestic): Rs. 315.00
- Kavya (Commercial): Rs. 1758.75
10
Detailed Output Report
- Consumer 1 (Ramesh):
Domestic connection, 120 units consumed.
Bill: Rs. 315.00 - Consumer 3 (Mahesh):
Commercial connection, 250 units consumed.
Bill: Rs. 1322.50 - Consumer 4 (Anita):
Domestic connection (Low Usage), 90 units.
Bill: Rs. 192.38 - Observation: Commercial rates create a steep increase in billing for similar consumption levels.
