I have this problem that Visual C++ does not let me use the method parameter as the size for an array I want to create. What am I doing wrong and how can this be done?

 void feld_links_rotieren(char a[], unsigned int n, unsigned int shift)
{
    shift = shift % n;

if (shift == 0)
{
    // Verschiebung um 0 Plätze ist zulässig. Funktion wird sofort verlassen.
    return;
}

// Ersten Teil isolieren
char first_half[shift];

TL;DR: Use `std::vector` – StoryTeller - Unslander Monica Nov 30 '17 at 17:13
it's for university and i am not allowed to use anything else than an array – Thomas Hahn Nov 30 '17 at 17:16
My condolences. Your teachers belong to the school of taught that argues for learning only half of the C++ language. You'll need to use dynamic memory allocation yourself. – StoryTeller - Unslander Monica Nov 30 '17 at 17:21
*It's for university and i am not allowed to use anything else than an array* -- Well go back to your university and ask them what to do, since arrays in C++ cannot be declared using a variable for the number of entries. – PaulMcKenzie Nov 30 '17 at 17:28

Unfortunately the salary of programming teachers is not adequate for programmers. So programming is taught by non-programmers. – Öö Tiib Nov 30 '17 at 19:43
