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?

(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.
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).

- (Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?arrow_forward(Written in C) Create a payroll program to store and calculate the payroll for a small company as follows:Create an array of floats that is 4 rows and 50 columns, with the columns being the number of employeerecords stored in the array.Program parameters are as follows:Create a menu in a function menu and call it with the following options (use a do-while loop):A or a to add employee infoD or d to display employee infoT or t to display total payrollS or s to display the info of all employeesC or c to display the count of employees present in the arrayF or F to delete a recordZ or z to exit programThe information for each employee is: employee number, hours worked, pay rate per hour, taxdeduction.Option A or a:Call the function possible to check and if the index returned is 50 then output a msg saying that thearray is full.

A credit card number must have between 13 and 16 digits. It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8arrow_forward
- (HTML & Javascript) Create a nested loop program that generates a multiplication table, but instead of a standard 10 by 10 table, the software allows the user to key in two numbers (the beginning and ending values), and then a multiplication table appears below it after pressing the button. When the user enters values that are out of range (between the values 2 and 10), the software will display a warning box that says "Please enter numbers between the values 2 and 10," and the computer will not create the desired result unless the user corrects the values.arrow_forward(HTML & Javascript) Create a nested loop program that generates a multiplication table, but instead of a standard 10 by 10 table, the software allows the user to key in two numbers (the beginning and ending values), and then a multiplication table appears below it after pressing the button.

- (Airline Reservations System) A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You’ll write a program to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1– 5). If the person types 2, then your program should assign a seat in the economy section (seats 6– 10). Your program should then print a boarding pass indicating the person's seat number and whether it’s in the first class or economy section of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding element of the array to 1 to indicate that the seat is no longer available.
