<p>Schreiben Sie ein C-Programm, welches die Zeichen und Wörter einer mit der Tastatur eingegebenen Zeile zählt. Wortzwischenräume sind entweder Leerzeichen (’ ‘) oder Tabulatoren (‘\t’). Die Eingabe der Zeile mit einem newline-character (‘\n’) abgeschlossen. Danach soll ihr Programm die Anzahl Zeichen und die Anzahl Wörter ausgeben und terminieren.</p>

Die Funktion <code class="docutils literal notranslate"><span class="pre">getchar</span></code> kehrt nicht gleich bei Eingabe des ersten Zeichens zurück, sondern puffert die Daten, bis die Eingabe einer kompletten Zeile mit Return abgeschlossen wird. Dann wird das erste Zeichen aus dem Puffer zurückgegeben und mit weiteren Aufrufen von getchar können die nachfolgenden Zeichen aus dem Puffer gelesen werden. Gibt <code class="docutils literal notranslate"><span class="pre">getchar</span></code> das Zeichen <code class="docutils literal notranslate"><span class="pre">\n</span></code> zurück, ist die Zeile komplett zurückgegeben und der Puffer ist wieder leer.</p></li>
