Write a program that computes the molecular weight of a carbohydrate (ingrams per mole) based on the number of hydrogen, carbon, and oxygenatoms in the molecule. The program should prompt the user to enter thenumber of hydrogen atoms, the number of carbon atoms, and the numberof oxygen atoms. The program then prints the total combined molecularweight of all the atoms based on these individual atom weights:Atom Weight(grams I mole)H 1.00794c 12.01070 15.9994For example, the molecular weight of water (H20) is: 2(1.00794) +15.9994 = 18.01528.
Airline companies apply baggage restrictions for their passengers. An
airline company has decided to apply a 10kg limitation for
passengers' hand luggage and 20kg for their normal baggage. When
passengers arrive, they enter their hand and normal luggage weight
from the keyboard. If passengers exceed their normal baggage
allowance of 10 dollars per gram, they pay 12 dollars per kg.
Accordingly, write the program that calculates the baggage price of
the airline they will go to according to the baggage values entered by
the arriving passenger and keeps this from closing the program for
each passenger. Note: If hand and normal baggage allowances are
stretched below the maximum value, the payment amount will be
considered not negative. An example printout is given on the right.

A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1)
The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:
a + bi + c + di = (a+c) + (b+d)i (addition)
a + bi − (c + di) = (a−c) + (b−d)i (subtraction)
(a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication)
(a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division)
You can obtain the Absolute Value for a complex number using the following formula:
|a + bi| = √(a2 + b2)
A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.

- 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: Input Result 62 5 10 89 6 0 45 BMI BMI < 18.5 18.5 s BMI < 25.0 25.0 ≤ BMI < 30.0 30.0 ≤ BMI 7 82 5 Interpretation Underweight Normal Overweight Obese 2 Enter weight (kg): Enter height (feet): Enter height (inches): BMI is 19.61, Normal Enter weight (kg): Enter height (feet): Enter height (inches): BMI is…arrow_forwardThe Café Noir Coffee Shop wants some market research on its customers. When a customer places an order, a clerk asks for the customer’s zip code and age. The clerk enters that data as well as the number of items the customer orders. The program operates continuously until the clerk enters a 0 for zip code at the end of the day. When the clerk enters an invalid zip code (more than 5 digits) or an invalid age (defined as less than 10 or more than 110), the program reprompts the clerk continuously. When the clerk enters fewer than 1 or more than 12 items, the program reprompts the clerk two more times. If the clerk enters a high value on the third attempt, the program accepts the high value, but if the clerk enters a negative value onthe third attempt, an error message is displayed and the order is not counted. At the end of the program, display a count of the number of items ordered by customers from the same zip code as the coffee shop (54984), and a count from other zip codes.

- A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that result from the fat using the following formula: Calories from fat = Fat grams × 9Next, she calculates the number of calories that result from the carbohydrates using the following formula: Calories from carbs = Carbs grams × 4Create an application that will make these calculations. In the application, you should have the following methods:• FatCalories–This method should accept a number of fat grams as an argument and return the number of calories from that amount of fat.• CarbCalories–This method should accept a number of carbohydrate grams as an argument and return the number of calories from that amount of carbohydrates.arrow_forwardWrite a program that calculates how much a person earns in a month if the salary is one penny the first day, two pennies the second day, four pennies the third day, and so on with the daily pay doubling each day the employee works.
