Answer to Question #319489 in C++ for Ajay

Question

Beyond 300 units Rs.5.00 per unit

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

of energy.

For the first 100 units Rs 1.50 per unit

For the next 200 untis Rs 3.00 per unit

All users are charged a minimum of Rs. 100. If the total cost exceeds Rs.250, then an additional

surcharge of 15% is added. Write a program to read the name of user and number of units consumed

and print out the charges with name.

Answer 1

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;


int main() {
    string name;
    int consumption;
    double charge;

    cout << "Enter a name: ";
    cin >> name;
    cout << "Enter a number of consumption units: ";
    cin >> consumption;

    if (consumption <= 100) {
        charge = consumption * 1.50;
    }
    else {
        charge = 100 * 1.50;
        if (consumption <= 300) {
            charge += (consumption - 100) * 3.00;
        }
        else {
            charge += 200 * 3.00;
            charge += (consumption - 300) * 5.00;
        }
    }
    if (charge < 100) {
        charge = 100;
    }
    if (charge  > 250) {
        charge *= 1 + 15/100.0;
    }

    cout << name << ": Rs. " << fixed << setprecision(2) << charge;

    return 0;
}
