C ++ ZU GROSS, UM ZU GEWINNEN
Ich habe ein voll ausgestattetes PPM-Zeichenprogramm in C ++ geschrieben, mit meiner eigenen Bitmap-Schriftart. Selbst wenn alle nicht benötigten Funktionen wegfallen, ist es im Vergleich zu den Antworten hier aufgrund der Definition für die Schriftart immer noch riesig.
Wie auch immer, hier ist die Ausgabe für HELLO WORLD:
