3. Compare the number of operations and time taken to compute Fibonacci numbers recursively versus that needed to compute them iteratively.

If a pointer is not pointing anywhere, it’s recommended you have it point to nothing. This is accomplished using NULL in C, as with int *p = NULL Why do you think that is a good idea? Explain your answer.

In Python, it's True to say each module creates its own global namespace, so variables with the same name, in different modules are completely isolated? If it's notTrue, then explain why? (T/F)

[C++ Programming] Please help tasks-3. Do not copy other solutions. Please write your own code to avoid doing same with others.

C++ Here is the original question for what it is worth. Please do not give me an answer you found on Chegg. I have one of those accounts too. Please read carefully, I have submitted this question several times and no one could follow directtions. I have my code doing what is asked of the problem with the exception of displaying the last_name, first_name A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file. Do not use arrays or sorting for this problem. Here is my...

Please Solve the Question in C++ as quickly as you can in 40 minutes. And do the same as asked in the question. Don't use extra things, please. Augment the safearay class in the ARROVER3 program in this chapter so that the user can specify both the upper and lower bound of the array (indexes running from 100 to 200, for example). Have the overloaded subscript operator check the index each time the array is accessed to ensure that it is not out of bounds. You'll need to add a twoargument constructor that specifies the upper and lower bounds. Since we have not yet learned how to allocate memory dynamically, the member data will still be an array that starts at 0 and runs up to 99, but perhaps you can map the indexes for the safearay into different indexes in the real int array. For example, if the client selects a range from 100 to 175, you could map this into the range from arr[0] to arr[75]. Note: Make this class into a template, so the safe array can store any kind of data....

Provide your own short C++ code example that uses a switch statement. Be sure to test and explain your code.

Which header file is necessary for C++ OOP? What attribute permits open recursion?

your goal is to modify your assignment 6 program to allow the user to pick up a random item and display a sorted list of the contents of the knap sack. note: if you use the built in c++, the most you can make on this assignment is 4 out of 10. you are expected to right your own sort based on one of the algorithms covered in class. your program should have the following: • the name of the program should be assignment 6. • 3 comment lines (description of the program, author, and date). • modify your assignment 5 program to do the following: o display a menu (use a switch statement to implement the menu) of actions ▪ attack: • for now, just display that the user chose to attack ▪ pick up item: • randomly add one of 6 items to an array named knapsack o you get to choose the item names • display which item the user picked up ▪ add an option to the main switch statement: display knap sack contents • the contents of the knap sack must be sorted The knapsack items are bananas, lays,...

What does it mean to have code that is portable in terms of C++? Please be specific.

List Out Differences Between Structures And Arrays?

To take use of OOP, which C++ header file should be included? Which (2) attribute allows for open recursion?

Create a list of some common C++ classes, and describe when each class is used.
