<p>In diesem Praktikum erstellen Sie mehrere kleine C-Programme, in denen Sie Input- und Output-Funktionen der C Standard Library verwenden.</p>
|
||||
<p>Arbeiten Sie in Zweiergruppen und diskutieren Sie ihre Lösungsansätze miteinander, bevor Sie diese umsetzen.</p>
|
||||
<p>Bevor Sie mit den Programmieraufgaben beginnen, setzen Sie eine virtuelle Maschine mit der vorbereiteten Praktikumsumgebung auf.</p>
