C PROGRAM FOR PRINTING ELECTRICITY BILLS

HERE IS THE INTERESTING CODE FOR THE PROGRAM WHICH READS THE CUSTOMER NUMBER AND UNIT OF POWER CONSUMPTION AND PRINTS THE BILL ACCORDINGLY.

  

#include<stdio.h>

#include<conio.h>

 

void main() {

 

   int cust_no, powerUsage;

   float amount;

   clrscr();

 

   printf("Enter the customer number: ");

   scanf("%d", &cust_no);

   printf("Enter the power consumed: ");

   scanf("%d", &powerUsage);

 

   if (powerUsage >= 0 && powerUsage <= 200)

      amount = powerUsage * 0.50;

   else if (powerUsage > 200 && powerUsage < 400)

      amount = 100 + ((powerUsage - 200) * 0.65);

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

      amount = 230 + ((powerUsage - 400) * 0.80);

  

   printf("Amount to be paid by customer no. %d is Rs.:%5.2f.", cust_no, amount);

 

   getch();

}
