- Please due in C++ If you don't mind answering the questions as short as possible? 1 what variable type did you use to store your temperatures and why? 2what variable type did you use to store the indices into your arrays and why? 3 what variable type did you use to store averages and why? 4 would you prefer not to use arrays in this scenario?arrow_forwardIt is better to have a deeper degree of access rather than a shallower level of access in terms of programming, therefore you shouldn't make your selection just on how well something performs.arrow_forwardC++ You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Example 1: diagram for example 1 attached Input: root = [4,2,7,1,3], val = 5 Output: [4,2,7,1,3,5] Explanation: Another accepted tree is: Example 2: Input: root = [40,20,60,10,30,50,70], val = 25 Output: [40,20,60,10,30,50,70,null,null,25] Example 3: Input: root = [4,2,7,1,3,null,null,null,null,null,null], val = 5 Output: [4,2,7,1,3,5] Constraints: The number of nodes in the tree will be in the range [0, 104]. -108 <= Node.val <= 108 All the values Node.val are unique. -108 <= val <= 108 It's guaranteed that val does not exist in the original BST.arrow_forward
- Use the example exe located here to create the pseudo code or flow chart that would represent the logic of the program. You must use an array to store each student's average. You must use looping (for or while, your choice) where appropriate (there will be many instances). Make sure you follow structured programming principles. Run the exe as much as needed on your computer to see how it works and examine the output file. You can answer most of your questions if you use the example file. There are several ways this can be done but the following must be incorporated. Input: Number of students (min 1, max 10) Number of grades for each student (min 1, max 10) The number of points each assignment is worth Enter each student's grade for each assignment Output: Total possible worth of all assignments At the end, the average for each student (must use array) written to screen At the end, the average for each student (must use array) written to the file StudentAverages.txt (example…arrow_forwardWhat steps are used to save local declarations in computer memory? If it is feasible to accomplish the same result without them, there are legitimate reasons not to employ them, although none are very compelling. If reference parameters can achieve the same effects, there is absolutely no need to use value parameters. What part do value parameters play in ensuring that a computer program makes the most of your data?arrow_forward
