Write a C program to input electricity unit charges and calculate total electricity bill by using the switch statement according to the given condition:
For the first 50 units Rs. 0.50/unit
For the next 100 units Rs. 0.75/unit
For the next 100 units Rs. 1.20/unit
For unit above 250 Rs. 1.50/unit
An additional surcharge of 20% is added to the bill.

#include<iostream> using namespace std; int main() { int unit; float amount,total_amount,s_charge; cout<<"enter the number of units you consumed"<<endl; cin>>unit; switch(unit<=50) { case 1: amount=unit*0.50; break; case 0: switch(unit<=150) { case 1: amount=25+(unit-50)*0.75; break; case 0: switch(unit<=250) { case 1: amount=100+(unit-150)*1.20 ; break; case 0: amount=220+(unit-250)*1.50; break; } break; } break; } s_charge=amount*0.20; total_amount=amount+s_charge; cout<<"your total bill is Rs"<<total_amount; } |
Output
enter the number of units you consumed
100
your total bill is Rs 75
