We can verify the file's contents. Of course, the file is not created in the current directory, so we have to go to chapter two, and then change to this folder, 02_10, list the output, and we can cat the challenge.txt file. There's the text I input. It seems like everything works. Yet I've place eight undefined behavior issues into this code that you must find, plus one bonus issue. These items are mentioned in this course, and they should be addressed to make this code run safe and in a predictable manner. Your task is to find and correct the various issues found in the exercise file. Modify the code as necessary, adding or removing statements, changing items, make it safe, and remove any undefined behaviors. Keep working with the code until you find and correct as many of the eight issues as possible…
