 * Program: Program 213d (Weather Forecasting)
 *
 * Description: This program is designed to find the temperature of the surrounding environment based on the amount of cricket chirps there are.
 * Variables used later in the program are first declared for clarity purposes.
 * The user is then asked for the amount of chirps in the environment.
 * The amount of chirps is the  converted to degrees fahrenheit, which itself is converted to degrees celsius.
 * The temperature in both celsius and fahrenheit is then printed for the user to see.
 * Finally, an if else decision tree prints a statement related to the severity of the temperature based on the temperature in degrees fahrenheit.
 *
 * Difficulties: I originally got a temperature of 0 celsius for all chirps, as I did not use doubles in the conversion ratio from fahrenheit to celsius.
 * Ex: (fahrenheit - 32) * (5 / 9) = (fahrenheit - 32) * 0 instead of (fahrenheit - 32) * (5.0 / 9.0)
 *
 * What I Learned: I got some more practice with mathematical calculations, primitive data types, and if else decision trees, and
