Textbook Question

Chapter 3, Problem 10PP

Repeat Programming Project 13 from Chapter 2 but in addition ask the user if he or she is:

a. Sedentary

b. Somewhat active (exercise occasionally)

c. Active (exercise 3–4 days per week)

d. Highly active (exercise every day)

If the user answers “Sedentary,” then increase the calculated BMR by 20

percent. If the user answers “Somewhat active,” then increase the

calculated BMR by 30 percent. If the user answers “Active,” then increase

the calculated BMR by 40 percent. Finally, if the user answers “Highly

active,” then increase the calculated BMR by 50 percent. Output the

number of chocolate bars based on the new BMR value.

13. The Harris–Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR.

The formula for the calories needed for a woman to maintain her weight is BMR=655+(4.3×weight in pounds)+(4.7×height in inches)−(4.7×age in years) The formula for the calories needed for a man to maintain his weight is BMR=66+(6.3×weight in pounds)+(12.9×height in inches)−(6.8×age in years) A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input his or her weight in pounds, height in inches, age in years, and the character M for male and F for female. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for the appropriate sex of the specified weight, height, and age.

Scenario As you surely know, due to some astronomical reasons, years may be leap or common. The former are 366 days long, while the latter are 365 days long. Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))

In python, a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.

in C# Sometimes figuring letter grades is hard. Write a program that asks for, and reads from the user, a midterm exam grade and a final exam grade. Compute the average of those two grades and ouput a letter grade based on the scale shown below. CHALLENGE PROBLEM: One of my graduate school classes modified the above calculation. This professor said that the final grade would be determined by the simple average of the midterm and the final, however, if the student scored better on the final than they did on the midterm, the professor would weight the midterm exam at 25%, and the final exam at 75% when computing the final grade. Modify your code to use this professors modification in determining letter grade. Here is the grading scale:
