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?
cpu_usage = [

(Replace strings) Write the following function that replaces the
occurrence of a substring old_substring with a new substring
new_substring in the string s. The function returns true if string s is changed,
and otherwise, it returns false.
bool replace_strings (string& s,
const string& old_string,
const string& new_string)
Write a test program that prompts the user to enter three strings, i.e., s,
old string, and new_string, and display the replaced string.
(Card Shuffling and Dealing) Modify the program you developed in Exercise 17.23 so thatit deals a five-card poker hand. Then write functions to accomplish each of the following:a) Determine whether the hand contains a pair.b) Determine whether the hand contains two pairs.c) Determine whether the hand contains three of a kind (e.g., three jacks).d) Determine whether the hand contains four of a kind (e.g., four aces).e) Determine whether the hand contains a flush (i.e., all five cards of the same suit).f) Determine whether the hand contains a straight (i.e., five cards of consecutive facevalues)

- (Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(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 the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forwardc++ onlyarrow_forwardQ3. (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_forward

- (Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b ≠ 0. Your program must be menu driven, allowing the user to select the operation (+, –, *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions: Function menu: This function informs the user about the program’s purpose, explains how to enter data, and allows the user to select the operation. Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the…arrow_forward(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…arrow_forwardC++ Programming point* go_far(point* other) Return the point bearing the x- and the y- coordinates of whichever x- and y-coordinates is further from the origin. Identify which of the two points have the furthest x- and y-coordinates independently. Example: this point has (-5, 1) and the other point has (4, 9). In the x-coordinate of the two points, -5 is further from the origin than 4. In the y-coordinate of the two points, 9 is further from the origin than 1. Hence, we return a new point bearing the coordinates (-5, 9).arrow_forward
- (Computer-Assisted Instruction) The use of computers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question correctly.arrow_forward(Use python):The instructor of a lower division statistics class has assigned you a task: make a function that takes in a student’s score on a scale from 0 to 100 and assigns a letter grade based on the following grade boundaries.arrow_forwardinteger) Write a function that computes the sum of the digits in an integer. Use the following function header:def sumDigits(n):For example, sumDigits(234) returns 9 (Hint: Use the % operator to extract digits, and the // operator to remove the extracted digit. For instance, toextract 4 from 234, use 234 % 10 To remove 4 from 234, use 234 // 10 (=23) Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits.arrow_forward
