Assignment
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 (testModel) 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 absolute values (i.e., mutlak değer) of the
differences between the model result and experimental result (see formula below) using a function.

- 1.Enter a positive integer value n (6 <= n < 30) and take n integers from the user as input and store them in array a. Then move the elements of this array one step to the left and make the first element of the array the last element of the array. Shift this array with a function. Display integer value n, the array elements in original order and the array elements in modified order (after shifting). For example, if the original order of the array a is like below : a: 33 45 67 89 12 7 After shifting one step to the left, you should get the following order of the array а: a: 45 67 89 12 7 33arrow_forwardOOP Lab #10 Using your knowledge in c++.

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. "Grades Average" to calculate each student Grade average, The grades average must be repented as letters e.g : A>= 90 , b>= 80 .. Then find the Maximum and Minimum Grade.
