Generating Electricity Bill In C with Algorithm

In this post we are going to make Electricity Bill in C 

Algorithm

1.  Declare all values

2.  Taking Customer ID

3. Taking Units Consumed by User

4. Making Conditions

5. Printing Total Bill In Proper Format

Code

#include <stdio.h>
void main()
{  
   int custid, conu;
   float chg, surchg=0, gramt,netamt;
   char x;

   printf("Input Customer ID :");
   scanf("%d",&custid);
   printf("Input the unit consumed by the customer : ");
   scanf("%d",&conu);
   if (conu <200 )
	chg = 1.20;
   else	if (conu>=200 && conu<400)
		chg = 1.50;
	else if (conu>=400 && conu<600)
			chg = 1.80;
		else
			chg = 2.00;
   gramt = conu*chg;
   if (gramt>300)
	surchg = gramt*15/100.0;
   netamt = gramt+surchg;
   if (netamt  < 100)
	netamt =100;
   printf("\nElectricity Bill\n");
   printf("Customer IDNO                       :%d\n",custid);
   printf("unit Consumed                       :%d\n",conu);
   printf("Amount Charges @Rs. %4.2f  per unit :%8.2f\n",chg,gramt);
   printf("Surchage Amount                     :%8.2f\n",surchg);
   printf("Net Amount Paid By the Customer     :%8.2f\n",netamt);

}

Output

Input Customer ID :1
Input the unit consumed by the customer : 584

Electricity Bill
Customer IDNO                       :1
unit Consumed                       :584
Amount Charges @Rs. 1.80  per unit : 1051.20
Surchage Amount                     :  157.68
Net Amount Paid By the Customer     : 1208.88
