Only statements within subroutine can view or modify local variables. Storage used by local variables is released when subroutine ends.

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 = [ [2, 2, 4, 2, 4, 1, 1, 4, 4, 12, 22, 23, 45, 9, 33, 56, 23, 40, 21, 6, 6, 2, 2, 3], # Monday [1, 2, 3, 2, 3, 2, 3, 2, 7, 22, 45, 44, 33, 9, 23, 19, 33, 56, 12, 2, 3, 1, 2, 2], # Tuesday [2, 3, 1, 2, 4, 4, 2, 2, 1, 2, 5, 31, 54, 7, 6, 34, 68, 34, 49, 6, 6, 2, 2, 3], # Wednesday [1, 2, 3, 2, 4, 1, 2, 4, 1, 17, 24, 18, 41, 3, 44, 42, 12, 36, 41, 2, 2, 4, 2, 4], # Thursday [4, 1, 2, 2, 3, 2, 5, 1, 2, 12, 33, 27, 43, 8,…arrow_forward
- C++ Programming Code two functions to fill an array with the names of every World Series-winning team from 1903 to 2020, then output each World Series winner with the number of times the team won the championship as well as the years they won them. The input file is attached, along with the main function and screenprint. Please note team names that include two words, such as Red Sox, have an underscore in place of the space. This enables you to use the extraction operator with a single string variable. The following resources are included: Here is main. #include <iostream>#include <fstream>#include<string> using namespace std; // Add function declarations and documentation here void fill(string teams[], int size);void findWinner(string teams[], int size); int main(){ const int SIZE = 118;int lastIndex;string team[SIZE]; fill(team, SIZE);findWinner(team, SIZE); return 0;} // Add function definitions here WorldSeriesChampions.txt…arrow_forwardThe program should allow the user to enter the age of the child and the number of days per week the child will be at the day care center. The program should output the appropriate weekly rate. The file provided for this lab contains all of the necessary variable declarations, except the two-dimensional array. You need to write the input statements and the code that initializes the two-dimensional array, determines the weekly rate, and prints the weekly rate. Comments in the code tell you where to write your statements. 1. Open the source code file named DayCare.cpp using Notepad or the text editor of your choice. 2. Declare and initialize the two-dimensional array. 3. Write the C++ statements that retrieve the age of the child and the number of days the child will be at the day care center. 4. Determine and print the weekly rate. 5. Save this source code file in a directory of your choice, and then make that directory your working directory. 6. Compile the source code…arrow_forwardIdentify the correct statements. Select ALL that apply. Question options: You can make your own custom modules. When a function is called, the item(s) inside the parentheses are called arguments. Global variables should be used in large programs. A variable declared inside main is inaccessible inside custom functions. Functions can be called inside other functionsarrow_forward
- Instructor note: Important Coding Guidelines: Use comments, and whitespaces around operators and assignments. Use line breaks and indent your code. Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code. Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable. A pedometer treats walking 1 step as walking 2.5 feet. Define a method named feetToSteps that takes a double as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. Then, write a main program that reads the number of feet walked as an input, calls method feetToSteps() with the input as an argument, and outputs the number of steps. Use floating-point arithmetic to perform the conversion. Ex: If the input is: 150.5 the output is: 60 The program must define and call a method:public static int feetToSteps(double…arrow_forwardassign(self, assignment:Assignment) -> AssignmentResult: """ This function is to simulate the process of the student receiving an assignment, then working on the assignment, then submitting the assignment and finally receiving grade for the assignment. This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later. Then an Assignment Result object should be created with the student's ID, the assignment…arrow_forwardPlease complete the exercise as instructed and do not use global variables.

It returns either True, if the username does end with digits, or False, if it does not. Check out the .isdigit method on strings!
