	// 1. Calculate the average of { 1, 2, 3, 4, 5 }
	// Two possible solutions: 
	System.out.println((1 + 2 + 3 + 4 + 5) / 5);    // int output
	System.out.println((1 + 2 + 3 + 4 + 5) / 5.0);  // double output
	// *But* what if you want the average of { 1, 3, 4, 5 }?
	// Need to use "floating point division" (divide by double)
	System.out.println((1 + 3 + 4 + 5) / 4.0);  // double output

	// 2. Everyone gets the same number of (whole) pizza slices. 
	int nSlices = 14;
	int nPeople = 4;
	// How many does each person get?
	int nPerPerson = nSlices / nPeople;    
	// How many are left over?
	int nLeftover = nSlices % nPeople;     
	System.out.println("Each person gets " + nPerPerson + " slices.");
	System.out.println("There are " + nLeftover + " left over.");
		
	// 3. What if there are more people than total slices?
	//    Write an if-statement that outputs an error if this is true.
	if (nPeople > nSlices)
	{
	    System.out.println("Error: not enough pizza!");
	}

	// In a real program, you would move this check up
	// before calculating nPerPerson and nLeftover.
