Input electricity unit charges and calculate total electricity bill
Calculate total electricity bill according to the given condition:
For first 50 units Tk. 1.50/unit
For next 100 units Tk. 2.25/unit
For next 100 units Tk. 3.00/unit
For unit above 250 Tk. 3.75/unit
An additional surcharge of 20% is added to the bill
Sample Output
Enter unit: 111 Total cost: 399.60 Process returned 0 (0x0) execution time : 1.793 s Press any key to continue.
Source Code
#include<stdio.h>
int main()
{
float unit, surcharge, taka;
printf("Enter unit: ");
scanf("%f", &unit);
if(unit >=1 && unit <= 50)
{
//For first 50 units Tk. 1.50/unit
taka = unit * 1.5;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
}
else if(unit >=51 && unit <=100)
{
//For next 100 units Tk. 2.25/unit
taka = unit * 2.25;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
}
else if(unit >=101 && unit <= 250)
{
//For next 100 units Tk. 3.00/unit
taka = unit * 3.0;
surcharge = taka * 0.2; //Surcharge 20%
taka = taka + surcharge;
}
else if(unit >=251)
{
//For unit above 250 Tk. 3.75/unit

}
printf("\nTotal cost: %0.2f\n\n", taka);
return 0;
}Sample Output
Enter unit: 500 Total cost: 2250.00 Process returned 0 (0x0) execution time : 3.293 s Press any key to continue.
