» Mehrdimensionale Felder

• Die zeichen einzelnen einscannen und direkt zu überprüfen ob Groß oder kleines alphabet, (es in groß buchstaben umwandeln??? wird das so verlangt in der übung? da ich ja nur großbuchstaben definiert habe)
  
• danach würde ich dem sagen, suche dieses zeichen im 1. Array und speichere das neue passende zeichen (aus dem 2. Array) in einer variablen.
  [Nur wie mach ich das??? 😕 😕 ]
