CPP Examples: If-Else

The LeVan Car Rental company charges $0.25/mile if the total mileage does not exceed 100. If the total mileage is over 100, the company charges $0.25/mile for the first 100 miles, then it charges $0.15/mile for any additional mileage over 100.
Write a program so that if the clerk enters the number of miles, the program would display the total price owed.

Source File

#include <iostream>
using namespace std;

void main()
{
unsigned int Miles;
const double LessThan100 = 0.25;
const double MoreThan100 = 0.15;
double PriceLessThan100, PriceMoreThan100, TotalPrice;

cout << "Enter the number of miles: ";
cin >> Miles;

if(Miles <= 100)
{
PriceLessThan100 = Miles * LessThan100;
PriceMoreThan100 = 0;
}
else
{
PriceLessThan100 = 100 * LessThan100;
PriceMoreThan100 = (Miles - 100) * MoreThan100;
}

TotalPrice = PriceLessThan100 + PriceMoreThan100;

cout << "\nTotal Price = $" << TotalPrice << "\n\n";
}

Here is an example of running the program:
  Enter the number of miles: 75

Total Price = $18.75
