28: W.A.P.
to calculate electricity bill.( <=100 RS.4 / units) >100 and <=300 Rs.
4.50 / units
>300
and <=500 Rs. 4.70 / units >500 Rs. 5/units.
Program:
#include <stdio.h>
#include <conio.h>
void main()
{
clrscr();
int unit;
printf("Enter the unit = ");
scanf("%d", &unit);
if (unit <= 100)
{
printf("\nYour electric
bill = %f", unit * 4.0);
}
else if (unit > 100 && unit <=
300)
{
printf("\nYour electric
bill = %f", unit * 4.50);
}
else if (unit > 300 && unit <=
500)
{
printf("\nYour electric
bill = %f", unit * 4.70);
}
else if (unit > 500)
{
printf("\nYour electric
bill = %f", unit * 5.0);
}
else
{
printf("\nWrong
Unit.");
}
getch();
}

Output:
Enter the unit = 440
Your electric bill =
2068.000000

Algorithm:
1.
START
2.
Declare
unit.
3.
Enter the
value of unit.
4.
If (unit
<= 100) then goto step 5 else goto step 6.
5.
Display
unit * 4.
6.
If (unit
> 100 && unit <= 300) then goto step 7 else goto step 8.
7.
Display
unit * 4.50.
8.
If (unit
> 300 && unit <= 500) then goto step 9 else goto step 10.
9.
Display
unit * 4.70.
10. If (unit > 500) then goto step 11 else
goto step 12.
11. Display unit * 5.
12. Display Wrong unit.
13. STOP.
