An electricity board charges the following rates to domestic users to discourage large consumption of energy:

FOR the first 100 units - 60P per unit

For next 200 units - 80P per unit

Beyond 300 units - 90P per unit

All users are charged a minimum of Rs.50.00. if the total amount is more than Rs.300.00 than an additional surcharge of 15% is added Write a C++ program to read the names of users and number of units consumed and print out the charges with names.

Implementation of above problem in C++ language:

#include<iostream.h>

#include<conio.h>

int main()

{

int no_unit;

float charge,scharge;

char name[20];

cout<<”\n enter name and number of units consumed”;

cin>>name;

cin>>no_unit;

if(no_unit<=100)

charge=(0.60*no_unit);

elseif(no_unit>100&&no_unit<=300)

{

charge=(100*0.60);

charge+=((no_unit-100)*0.80);

}

elseif(no_unit>=300)

{

charge=(100*0.60);

charge+=(200*0.80);

charge+=((no_unit-300)*0.90);

}

if(charge<50)

charge=50;

if(charge>300)

{

scharge=(0.15*charge);

charge+=scharge;

}

cout<<”electricity bill \n”;

cout<<name<<” : : rs”<<charge;

getch();

return(0);

}
