// Everything in main is commented out because it

// 
// Read the comments in main to see how the code

// YOUR FUNCTIONS HERE









// END YOUR FUNCTIONS - DO NOT EDIT MAIN (except to uncomment things to test)

	//Add, multiply functions

	//cout << multiply(5, 3) << endl; // 15
	//cout << multiply(7, 10) << endl; // 70

	//Implement biggest and smallest functions.
	//cout << biggest(10, 2.2, 7) << endl;  // 10
	//cout << biggest(4.9, 5, 5) << endl; //5
	//cout << biggest(8, 10, 20.3) << endl; //20.3

	//cout << smallest(6, 20, 3) << endl; //3
	//cout << smallest(3.14, 1.17, 8.3) << endl;  //1.17

    // hint: think division

	//Create a function that sums the numbers between the given range
	//int total1 = sum(8, 20);  //this should be 8+9+10+...+20 =

	//cout << "The sum from 8 to 20 is " << total1 << endl;
	//cout << "The sum from 9 to 35 is " << total2 << endl;

    //Create a function that calculates power (x raised to the y) WITHOUT using the built-in pow function
    // (yes same as the hw, but lots of people just called pow which it tots cheats - if you didn't, you
    //  already know the answer here)

	//cout << "4 raised to the 5 is " << power(4, 5) << endl;    // 1024
	//cout << "14 raised to the 3 is " << power(14, 3) << endl;  // 2744

	// Okay, now something more interesting!
    // Prime numbers cannot be evenly divided by any number smaller than them except 1
    // hint: computers don't mind doing lots of divisions

    // Write a function that lists all the prime numbers from 1 up to a certain number
	// hint: Functions may call other functions, even other functions that *you* have written.
	
	//listPrimes(10); //Should print: 2,3,5,7
	//listPrimes(20); //Should print: 2,3,5,7,11,13,17,19
