Hey guys, an AO member has asked me to write a tutorial on file input and file output in C++. In this tutorial I plan to teach the readers how to open and close a file, how to read the contents of a file, how to write into a file, how to check to see if a file exists, and how to copy the content of one file into another file. If you guys have any other suggestions, please let me know ASAP because i am almost finished writing this tutorial.
