Write a C program to generate electricity bill.

 Write a C program to generate electricity bill.

Program:

#include <stdio.h>

int main() {

    int units;

    float bill = 0;

    // Input customer details and units consumed

    printf("Enter electricity units consumed: ");

    scanf("%d", &units);

    // Bill calculation based on slab rates

    if (units <= 100) {

        bill = units * 1.5;

    } else if (units <= 200) {

        bill = (100 * 1.5) + ((units - 100) * 2.0);

    } else if (units <= 300) {

        bill = (100 * 1.5) + (100 * 2.0) + ((units - 200) * 3.0);

    } else {

        bill = (100 * 1.5) + (100 * 2.0) + (100 * 3.0) + ((units - 300) * 5.0);

    }

    // Adding a fixed meter charge (optional)

    float meterCharge = 50.0;

    float totalBill = bill + meterCharge;

    // Output

    printf("\n------ Electricity Bill ------\n");

    printf("Units Consumed : %d\n", units);

    printf("Energy Charges : ₹%.2f\n", bill);

    printf("Meter Charges  : ₹%.2f\n", meterCharge);

    printf("Total Bill     : ₹%.2f\n", totalBill);

    printf("------------------------------\n");

    return 0;

}

Output:
