Chapter 3, Problem 5P
Write a
Degrees_C = 5(Degrees_F- 32)/9
Degrees_F- (9 (Degrees_C) /5) + 32)
Prompt the user to enter a temperature and either a C or c for Celsius or an F or f for Fahrenheit. Convert the temperature to Fahrenheit if Celsius is entered, or to Celsius if Fahrenheit is entered. Display the result in a readable format. If anything other than C, c, F, or f is entered, print an error message and stop.

Body Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters.
Write a program which prompts the user to enter the weight in kgs (integer value) and height in feet and inches (both integers) and then calculates the BMI of the person. Your
program first need to convert inches to meters (i.e. inches * 0.0254) and then use the following formula to calculate BMI:
weight kilogram / (height_meter)^2
Your program displays the BMI value in two decimal places and the corresponding status as shown in the examples below. Note that one inch is 0.0254 meters and 1 foot is 12
inches.
For example:

Meadowdale Dairy Farm sells organic brown eggs to local customers. It charges $3.25 for a dozen eggs, or 45 cents for individual eggs that are not part of a dozen. Write a program that prompts a user for the number of eggs in the order and then display the amount owed with a full explanation using the following wording: You ordered 27 eggs. That’s 2 dozen at $3.25 per dozen and 3 loose eggs at 45 cents each for a total of $7.85.
So far everything is right but something in my equations is causing my ouput to show up as 45.0
