Write a program to calculate electricity bill

Write a program to calculate electricity bill. Read the starting and ending meter reading.

The charges are as follows.

No. of units consumed Rates in (Rs.)

200–500	3.50
100–200	2.50
Less than 100	1.50

Solution

void main()
{
int initial,final,consumed;
float total;
clrscr();
printf(“\n Initial & Final Readings :”);
scanf(“%d %d”, &initial, &final);
consumed = final-initial;
if(consumed>=200 && consumed<=500)
total=consumed * 3.50;
else if(consumed>=100 && consumed<=199)
total= consumed * 2.50;
else if(consumed<100)
total=consumed*1.50;
printf(“Total bill for %d unit is %f”,consumed,total);
getche();
}

Output

OUTPUT:

Initial & Final Readings : 800 850

Total bill for 50 unit is 75.000000
