- Write a code segment that creates an ofstream object named outfile, opens a file named numbers.txt, and associates it with outfile. The code should then use a loop to write the numbers 1 through 100 to the file before closing it.arrow_forwardYou are to write a C++ function that given the name of a file passed as a string, the function will dynamically create an ofstream object. The function will open the file with the provided name. It will then make sure that the file properly opened. The function will then return a pointer to the ofstream object that was created.arrow_forwardA StreamReader object's ReadLine function shouldn't be called until the EndOfStream property has been checked.arrow_forward

That way, no changes are lost, even if the program crashes laterarrow_forwardO O An object of the fstream class, so what is the default mode to open the file the default mode depends on the compilerarrow_forward
- Write a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.arrow_forward2. File handling is an important part of any application. Assume that, you are asked to build an application to find the harmonic mean in a file. Assume that you have to read the file of "Filel.txt" and print the harmonic mean of each row to an output file "File2.txt". All of the data in the "File1.txt" is comma separated. In file1.txt you are given the name of the data set in first place, then you are given the data list. All of them are comma separated. Your task is to compute the harmonic mean from the given file | for each dataset. The file may contain more than 1000 rows. Write your code by following the requirements. File2.txt harmonic mean of Datal is 3.50 harmonic mean of Data2 is 3.43 harmonic mean of Data3 is 3.50 File1.txt Data1, 3, 4, 4, 3, 3.7, 4, 3.3, 1 Data2, 3, 4, 3.7, 3, 3.7, 4, 3, 1 Data3, 3, 4, 4, 3, 3.7, 4, 3, 2 Data4, 3, 4, 4, 3, 3.7, 4, 3.3, 2 Design a JAVA application that can perform the task with the given scenario. harmonic mean of Data4 is 3.49arrow_forwardIN C++ Write a program that represents a playlist on a video streaming service.

You will also need to provide a menu that shows and performs the various options above. The menu should continue to display until the user selects the "Exit playlist" option. A description of each menu option is listed below: Add video to list Prompts the user for a video title and total minutes Then your code stores the video onto the storage object of your choice Remove video from list Prompts the user for a video title Then your code removes that video from your storage object Display list in alphabetical order Displays the video's title and total minutes for each video in your storage object.
