17: recursion.cpp) Write two recursive integer functions. The first function should calculate factorials using the definition 0! = 1 and n! = (n-1)! x n. In addition, if n is too large it should be able to detect integer overflow before it happens. The next function should calculate the greatest common factor (gcf) of two numbers. If the second number is zero, then the gcf is the other number. Otherwise, the gcf of a and b is the same as the gcf of b and a mod b.

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…

can you help with a C++ code for the following: This is to create a prototype for a Web browser. You’ll do this by transforming the file viewer created (SHOWN BELOW) into a browser for a web of files that are all located on a single computer. (This is in contrast to the real World Wide Web whose pages are located all over the world.) Details The files in this web of files are plain text files that may contain anchors that provide links to other files. More precisely, an anchor is a string of the form 1 where filename is the name of another file and text is a piece of text. For example, here’s a line of text that contains an anchor: More is available. To keep things simple, assume that every anchor is separated from adjacent text by white space and that the strings filename and text cannot contain white space. Your browser should work exactly like the file viewer, except for the following: 3. The browser should have another new command called back that reopens the previous file. This…
