1. Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a function drive that simulates driving the car for a certain distance, reducing the fuel level in the gas tank, and functions get_gas, to return the current fuel level, and add_gas, to tank up. Sample usage:
Car my_beemer(29); // 29 miles per gallon
my_beemer.add_gas(20); // Tank 20 gallons
my_beemer.drive(100); // Drive 100 miles
cout << my_beemer.get_gas() << "\n"; // Print fuel remaining
2. Write a program that produces ten random permutations of the numbers 1 to 10. To generate a random permutation, you need to fill a vector with the numbers 1 to 10 so that no two entries of the vector have the same contents. You could do it by brute force, by calling rand_int until it produces a value that is not yet in the vector. Instead, you should implement a smart method.
- Make a second array and fill it with the numbers 1 to 10. Then pick one of those at random, remove it, and append it to the permutation vector.
- Repeat ten times.
