- Exercise 1: 1) Declare and initialize an array of 10 double values. Assign random values to each array element. Hint: You need to use the Random class library. 2) Traverse this array and print all the values. 3) Sort the values in this array in descending order and print all the values. Exercise 2: 1) Declare and initialize an array that keeps records of 10 items. Each item has a name, quantity in stock, and a sale price. Assign random values to numeric fields of each new item, and give sequential item names to each of them: "Item #01". "Item #02," "Item #03," ... Hint: You need to use the Random class library. 2) Traverse this array and print all the items. 3) Sort the values in this array in ascending order of quantity in stock and print all the items.part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)You can copy all elements of one array into one another with an assignment statement.

Find the Culprit by CodeChum Admin "Help!!!" Someone's calling for help! It seems that someone was robbed and their phone was stolen. Luckily, the phone's GPS is turned on so we can track the culprit's coordinates! Instructions: Ask the user for the number of rows and columns of a 2D array and then its elements. Then, ask the user for another integer value which represents the culprit. Finally, go through the 2D array and find the culprit's coordinates - its row number and column number and display them. Input 1. Number of rows 2. Number of columns 3. Elements of the 2D array 4. Culprit's value Output Print the row of the position first and then the column of the position. Note that the row and the column is 0-based (i.e. it starts at 0 and not at 1). It is guaranteed that the culprit exists only once in the 2D array. Enter # of rows: 4 Enter # of columns: 4 Elements: 1 4 2 3 9 1 2 3 4 2 1 1 9 2 8 3 Enter the culprit's value: 8 Culprit's·position: 3, 2Return the maximum value from the provided integer array.
