    //  The ignore function is predefined in iostream. Its
    //  purpose is simply to ignore, one character at
    //  a time, any input defined in its call statement
    //  defined as ignorable by position or type.from the
    //  input buffer. This means your program can ignore
    //  white space one character at a time, or perhaps all
    //  white space besides new line characters, just tabs,
    //  or any other useful combination. Your program might
    //  also ignore all numeric or nun numeric input, or
    //  perhaps accept only input within predefined ranges.
    //  Given an input buffer that looks like this:

    	25 67 48 19
    	13 579 10 38

    //  Your code might look like this:

    	cin >> a;
    	cin.ignore(100, '\n');
    	cin >> b;

    //  This code reads the first input from each line of
    //  input, discarding the remainder from each line of
    //  buffer input. Another sequence might be:

    	25 67 48 19     //  comments here
    	13 579 10 38    //  comments here

    	while(cin.ignore(100, '/')){
    	  cin.ignore(100, '/');
    	  while(cin.get(ch))
    	    cout << ch;
    	  cout << endl;
    	}

    //  This code will output only the comments from the
    //  input, displaying them on the monitor. Ignore()
    //  is used to bypass delimiters and other content.
