# Program to calculate and print the electricity bill of a given customer. The customer ID, name, and unit consumed by the user should be captured from the keyboard to display the total amount to be paid to the customer.

Here, we have a basic program example to calculate the electricity bill using different languages. The charge are as follow : Unit  Charge/unit

upto 199   @1.20

200 and above but less than 400  @1.50

400 and above but less than 600  @1.80

600 and above    @2.00

If bill exceeds Rs. 400 then a surcharge of 15% will be charged and the minimum bill should be of Rs. 100/-

This program is created in c language, c++, Java, and Python.

## Program to calculate electricity bill in C language

```#include <stdio.h>
#include <string.h>
void main()
{
int cust_id, unit_consumed;
float charge, sur_charge=0, gramt,net_amt;
char cust_name[25];

printf("Input Customer ID :");
scanf("%d",&cust_id);
printf("Input the name of the customer :");
scanf("%s",&cust_name);
printf("Input the unit consumed by the customer : ");
scanf("%d",&unit_consumed);
if (unit_consumed <200 )
charge = 1.20;
else	if (unit_consumed>=200 && unit_consumed<400)
charge = 1.50;
else if (unit_consumed>=400 && unit_consumed<600)
charge = 1.80;
else
charge = 2.00;

gramt = unit_consumed*charge;
if (gramt>300)
sur_charge = gramt*15/100.0;
net_amt = gramt+sur_charge;
if (net_amt  < 100)
net_amt =100;
printf("\nElectricity Bill\n");
printf("Customer IDNO                       :%d\n",cust_id);
printf("Customer Name                       :%s\n",cust_name);
printf("unit Consumed                       :%d\n",unit_consumed);
printf("Amount Charges @Rs. %4.2f  per unit :%8.2f\n",charge,gramt);
printf("Surchage Amount                     :%8.2f\n",sur_charge);
printf("Net Amount Paid By the Customer     :%8.2f\n",net_amt);

}
