# Coding Practice¶

How long is a year on other planets? Let’s write a program that prints out the number of days in a year on each planet using a switch statement. These values are, in planetary order, 88 days, 225 days, 365 days, 687 days, 4333 days, 10759 days, 30687 days, and 60190 days. Print out this information in the following format: Planet planet has numDays number of days in a year! Select the Parsonsprob tab for hints for the construction of the code.

Now let’s generate a BingoBoard! We want to fill the 25 Spaces on the BingoBoard with random values from 1 to 75 without repititon. To do this, we’ll make a vector of numbers from 1 to 75 and shuffle it using the same method as shown in this chapter. Then we will select the first 25 values for the 25 spaces on the BingoBoard. We will do this entire process in multiple steps. First, write the function randomInt, which generates a random value between low and high, inclusive. Be sure to include the relevant libraries!

Now that we have the functions randomInt and swapValues, we can write the function generateRandVec. generateRandVec creates a vector with values from 1 to 75, shuffles it using randomInt and swapValues, and returns the shuffled vector.

Let’s print out our BingoBoard! Write the BingoBoard member function printBoard. Insert tabs between each value in each row to make the board print out neater. Select the Parsonsprob tab for hints for the construction of the code.

You may have noticed that in some cases, our version of bubbleSort does an unnecessary amount of work. For example, if our vector was {1, 2, 3, 5, 4}, bubbleSort would swap 4 and 5, but then keep going even though our vector is already in order! We can save some work by including a bool called is_changed. If we swap values during a pass, we set is_changed to true. If nothing has been swapped, then is_changed stays false, and we know to break out of the loop since our vector is already sorted. Write the function fastBubbleSort, which is bubbleSort with this modification. Select the Parsonsprob tab for hints for the construction of the code.
