#include<stdio.h>

#include<string.h>

#include<conio.h>

void main()

{ int cust_no, unit_con;

float charge,surcharge=0, amt,total_amt;

char nm[25];

clrscr();

printf("enter the customer IDNO :\t");

scanf("%d",&cust_no);

printf("\nenter the customer Name :\t");

scanf("%s",nm);

printf("\nenter the unit consumed by customer :\t");

scanf("%d",&unit_con);

if (unit_con <200 )

charge = 1.20;

else if (unit_con>=200 && unit_con<400)

charge = 1.60;

else if (unit_con>=400 && unit_con<600)

charge = 2.00;

else

charge = 2.50;

amt = unit_con*charge;

if (amt>300)

surcharge = amt*15/100.0;

total_amt = amt+surcharge;

if (total_amt < 25)

total_amt =25;

clrscr();

printf("\t\t\tElectricity Bill\n\n");

printf("Customer IDNO :\t%5d",cust_no);

printf("\nCustomer Name :\t%s",nm);

printf("\nunit Consumed :\t%5d",unit_con);

printf("\nAmount Charges @Rs. %4.2f per unit :\t%8.2f",charge,amt);

printf("\nSurchage Amount :\t%8.2f",surcharge);

printf("\nNet Amount Paid By the Customer :\t%8.2f",total_amt);
