# Coding Practice¶

A binary number is one that is expressed in the base-2 numeral system. Write a function convertToBinary which takes a decimal as a parameter. convertToBinary takes the number in decimal, converts it into a binary number, and returns the binary number. Test your function in main. Run and test your code! Select the Parsonsprob tab for hints for the construction of the code.

The astronomical start and end dates of the four seasons are based on the position of the Earth relative to the Sun. As a result, it changes every year and can be difficult to remember. However, the meteorological start and end dates are based on the Gregorian calendar and is easier to remember. Spring starts on March 1, summer starts on June 1, fall starts on September 1, and winter starts on December 1. Write a function called birthSeason, which takes two parameters, month and day. birthSeason calculates which season the birthday falls in according to the meteorological start and returns a string with the correct season. For example, birthSeason (7, 5) returns “summer” since July 5 is in the summer. Select the Parsonsprob tab for hints for the construction of the code. Run and test your code!

A number is a common factor of two other numbers if it divides evenly into both of the other numbers. For example, 2 is a common factor of 4 and 18, because 2 goes evenly into 4 and 18. Write the function isCommonFactor, which takes three parameters, num1, num2, and factor. isCommonFactor returns true if factor is a factor of both num1 and num2, and returns false otherwise. Run and test your code! Select the Parsonsprob tab for hints for the construction of the code.

In the enchanted Mushroom Forest, there are many different types of mushrooms as far as the eye can see. Most of these mushrooms can make delicious stews and dishes, but some of them are poisonous. Write the function isPoisonous, which takes an char size, int numSpots, and bool isRed as parameters. If a mushroom is large (‘L’) and has fewer than 3 spots, it is poisonous. If a mushroom is small (‘S’) and is red, it is poisonous. If a mushroom has fewer than 3 spots or is not red, it is poisonous. Otherwise, it is not. isPoisonous should return true if the mushroom is poisonous and false otherwise. Run and test your code! Select the Parsonsprob tab for hints for the construction of the code.

Write the function digitSum which takes an int num as a parameter and returns the sum of all its digits. For example, digitSum (1423) would return 10. Use recursion. Run and test your code! Select the Parsonsprob tab for hints for the construction of the code.
