Answer:

#include <stdio.h>

#include <string.h>

void main()

{

int custid, conu;

float chg, surchg=0, gramt,netamt;

char connm[25];

printf("Input Customer ID :");

scanf("%d",&custid);

printf("Input the name of the customer :");

scanf("%s",connm);

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("Customer Name :%s\n",connm);

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);

}
