A scientist has developed a mathematical model for a physical process, and he wants to check how
good is model is. To evaluate the correctness of his model, he wants to test the results of his model
under certain parameters and compare them with experimental results.
Write a program that first reads the number of tests (testCount) as an int followed by the results of
each test according to the model as a double array (test Model) and finally the results of each test
according to experiments as a double array (testExperiment). Then, the program should calculate
the error of the model by evaluating the average of the squares of the differences between the model
result and experimental result (see formula below) using a function.

You have been hired at an open-air mine. You are to write a program to control a digger. For your task, you have been given a 'map' of all the underground resources in the mine. This map comes as a two-dimensional integer array. The array has n rows and k columns. Each integer is between zero and one hundred (inclusive). This array represents a grid map of the mine – with each row representing a different height level. Each square in the grid can contain valuable resources. The value of these resources can go from zero (no resources) to 100 (max resources). The grid maps the resources just below the surface, and down to the lowest diggable depths. The digger starts at the surface (so, just on top of the topmost row in the grid)—at any horizontal position between 1 and k. The digger cannot dig directly downwards, but it can dig diagonally in either direction, left-down, or right-down. In its first time-step, it will dig onto the first row of the grid. In its second time-step, it'll hit…

Demonstrate a project that contains a file called "Class Grades.txt", then read student's names and Grades from the file and store them into separate arrays, and then do the following: 1. Firstly, you create a ID string array called “names" to store each student name. 2. Secondly, you create a 2D int array "grades" to store student's original quizzes Grades. the array has 7 columns, the original 6 Quizzes Grades must be stored in the following columns : [0,1,2,3,4,5]. Store in the last column the average of the Grades. 3. Thirdly, Get the grades from the array called "grades", then calculate the average and determine the letter of that final grade. Hint: The following functions are required: 1. "PutGrades" to read and save data into both "names" and "grades" arrays. 2.

- In a C++ program, you need to store the ID's and GPS's for 25 students. 1. Define 2 arrays that may be used in parallel to store the ID's and GPS's. 2. Write a loop to print the ID and GPA arrays in columns, with column headings. Put the information for each student on its own line.arrow_forwardI need the code from start to end with no errors and the explanation for the code ObjectivesJava refresher (including file I/O)Use recursionDescriptionFor this project, you get to write a maze solver. A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # # ## # # #### # ## ##### ## ########## RequirementsWrite a MazeSolver class in Java.

Your program can display the valid exits found in any order. See the examples below for exact output requirements. Also, record…arrow_forwardIn this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…arrow_forward

Take note the user will be the one to decide the number of rows and columns, and will be the onė to input the elemets of the array. Let the program display the matrix.

- Write a program that takes numbers from the user and places them into an array. After each new entry from the user, the program prints out the current array of numbers. Several rules must be followed: Each new number is checked and added to the array ONLY if it is larger than the number in the previous position in the array. This condition is not checked for the first number.In other words, the new number is rejected and nothing is added to the array if the entry is too-small. The new number is added to the array EXCEPT: when the user enters a number greater than 75, the number 0 is added to the array instead. when the user enters a multiple of 7 (and less than or equal to 75), the number 7 is added to the array instead. The program exits after 10 numbers have been placed into the array. Programming requirements: You must define and call at least one function. I recommend printArray(...) You must use at least one array. Assume the entries are integers Example Test Case:…arrow_forwardWrite a program, Passwords , that contains an array of five names and another array of five passwords. Your program should ask the user to enter a name and a password. If the user enters the correct name with its related password, grant access (e.g. display “Access granted!”). IF the user enters the wrong name/password (can be either or both), allow the user to re-try only once. If the user still cannot enter the correct name/password, display the following: “Sorry, your username/password does not match our database. Contact the administrator.”arrow_forwardPlease submit your solution to the lab instructor once you have your program working. Your lab instructor will tell you how (s)he would like you to turn it in. Failure to submit will result in a zero. Write a program that asks the user to input two integers a and b. Then create an array that has all integer from a to b. Print out the array. (Don’t forget to consider the situation of a=b, a<b, and a>b.) Example 1: Input two numbers: 6 2 Array is [6, 5, 4, 3, 2] Example 2: Input two numbers: 4 8 Array is [4, 5, 6, 7, 8] Pass the above array as a parameter to a method called average and return the average and print it out in the main method.
