Wie kann ich Text "ausgerichtet" formatieren, damit er für eine bestimmte Breite links und rechts ausgerichtet wird?

int main()
{
    printJustified("A long text with many words. "
        "A long text with many words. "
        "A long text with many words. "
        "A long text with many words. "
        "A long text with many words.");
}
