Chapter 6, Problem 6.14E
(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statement
Y = floor (x * 10 + 0.5) /10:
rounds x to the tenths position (the first position to the right of the decimal point). The statement
Y = floor (x * 100 + 0.5) /100:
rounds x to the hundredths position (the second position to the right of the decimal point). Write
a) roundTolnteger(number)
b) roundToTenths (number)
c) roundToHundredths(number)
d) roundToThousandths (number)
For each value read, your program should print the original value the number rounded to number rounded to the neatest integer, the number rounded to the nearest tenth, the number rounded to the hundred and the number rounded to the nearest thousandth.

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

Factorial) The factorial of a nonnegative integer n is written n! (pronounced “n factorial”) and is defined as follows:For example, 5!= 5.4.3.2.1 , which is 120. Use while statements in each of the following:A. Write a program that reads a nonnegative integer and computes and prints its factorial.B. Write a program that estimates the value of the mathematical constant e by using the formula:Prompt the user for the desired accuracy of e (i.e., the number of terms in the summation).C. Write a program that computes the value of by using the formula Prompt the user for the desired accuracy of e (i.e., thenumber of terms in the summation).
Q2) (Perfect Numbers) An integer number is said to be a perfect number if its factors,
including 1 (but not the number itself), sum to the number. For example, 6 is a perfect
number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number
is a perfect number. Use this function in a program that determines and prints all the perfect
numbers between 1 and 1000. Print the factors of each perfect number to confirm that the
number is indeed perfect. Challenge the power of your computer by testing numbers much
larger than 1000.

- Please answer item number 4. (pyhthon programming)arrow_forwardFilling the Pool (Deprecated) Write a program that calculates the time neccessary to completely fill an empty pool with water. We will assume that the pool is rectangular and the depth is uniform. All input values in this program will be integers. Prompt the user to enter the pool dimensions - length, width, and depth (unit: feet) - as well as the rate at which water can be put into the pool (unit: gallons per minute). Using these values, calculate and display the time (in minutes) needed to fill the pool from completely empty to completely full. Note: you should calculate the volume of the pool (as cubic feet) and then determine the rate (in cubic feet per minute) that water can be put into the pool. Assume that there are 7.48 gallons in one cubic foot. Your program should run like the examples shown below: Enter pool dimensions Length: 10 Width: 8 Depth: 7 Water entry rate: 14 The pool will fill completely in 299.2 minutesarrow_forwardComputer Sciencearrow_forward

- Functions Exercise (Parking Charges) A parking garage charges a $2.00 minimum fee to park for one hour. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and prints the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday's receipts. The program should use the function Charge to determine the charge for each customer.

- Q3. (Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 10,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7). 1 2 3 4 5 1 2 4 6 7 3 4 6 7 3 4 5 7 8 9 4 7 8 9 10 7 8 10 11 7 10 11 12 Row\Col 3.arrow_forwardFunctions & Loops : Case Studies Prompt the user to input two positive integers.

Use Call-by-Value. oddNumbers() is a void function. Output the sum of all even numbers between firstNum and secondNum. (use while loop); create a user-defined function called sumEvenNumbers(). Use Call-by-Value. Declare a variable called sumEven in the main() for the sumEvenNumbers(). sumEvenNumbers() is a value returning function. Use sumEven to hold a returned value.
