         * Here is the important part:
         *
         * 1)We create a new output stream which will be used to save data into the file
         * In this case the 'ofstream'constructor needs the filename and the stream type
         *  a)IMPORTANT: The filename path must be a C 'char' type and not a string, so we convert the string
         *  using the 'cstr()' function
         *  b)In this case we want to create an output file which will contain ASCII data hence we use
         * the ios::out' modifier
         *
         * 2)We use the ofstream the same way we use the 'cout' stream. With the '<<' operator we throw data in
         * the stream which are in turn saved into the file
         *  a)IMPORTANT: Note that we break the line after each variable by saving 'n'
         *  This is necessary here because if we don't, when reading the file the multiple variables will be considered
         *  as one variable.
