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 = [

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.

- 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_forward(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.arrow_forward( (A + B ) * (C – D) + E / F ) – G Using manual and algorithmic methods, write the following expression to postfix form:arrow_forward
- (Random sentences and story writer) Write an app that uses random-number generation to create sentences. Use four arrays of strings, called article, noun, verb andprepostion. Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article, noun.As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forward5.

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

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_forward
- ( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the…arrow_forward4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forward4.
