Chapter 3, Problem 6PP
Repeat
- 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.” thon 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.

Write a program that can suggest an activity based on the temperature. If the temperature is between 20 to 40 degrees Fahrenheit, suggest the user go skiing; if the temperature is between 41 to 60 degrees Fahrenheit, suggest the user go hiking; if the temperature is in the range of 61 to 80, suggest swimming. For all the temperatures out of these ranges (too cold or too hot), then suggest staying inside.
C++ Programming Exercise:
A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit?
Write a program that prompts the user to enter:
a. The total number of of units.
b. The rent to occupy all the units.
c. The increase in rent that results in a vacant unit.
d. Amount to maintain a rented unit.
The program then outputs the number of units to be rented to maximize the profit.
Write a program that will figure out the required change for a purchase. Start by asking the user for the price of the product and the amount paid. (We are expecting that the user will give a larger value for the amount paid.) Read in each of these values as a double. Report back to the user the number of each denomination of change due. You are not just telling the user the amount of money he gets back.
Hint: Working with integers is much easier. The modulo operator is your friend for this assignment. Also, note that pennies can be tricky due to the poor real number to binary conversions. (Remember that 1.00 could actually be stored as 0.9999999999997.)
Do not include five-dollar bills, ten-dollar bills, etc. Only show coins and one-dollar bill amounts. Be sure to test multiple values.
There is a test case below. Your program should run the test case exactly as it appears below, and should work on any other case in general.
