Given the Array declaration below, determine the output: int T[8] = {2, 3, 7, 9, -1, 2, 4, 5};   int x = 5;  cout << T[x-2] / T[12-2*x];    int y = -3; cout << pow(T[y+4],T[3-y]);

Description of the assignment: Your program should read in a set of grades (that are all integers) entered by the user. The user will signify the end of the list of grades by entering -999. Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data. Then, your program should calculate the mean and standard deviation for the remaining set of grades, and print these out to two decimal places. Finally, a histogram for this data (without the highest and lowest grades) should be printed out as well. Your program should include the following functions: void readGrades (double grades [], int *n); /* This function reads an…

Part 2: Unroll Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: const square = [ [1, 2, 3, 4], [5, 6, 7, 8], ]; [9, 10, 11, 12], [13, 14, 15, 16] unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top- left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].
