 string menuNames[menuAmount];
    
    for(int i=0;i<menuAmount;i++)
    {        
        menuNames[i]=menuNamesAfterParse.substr(0, menuNamesAfterParse.find_first_of('|') );
        if(i!=(menuAmmount-1))
        {
            menuNamesAfterParse = menuNamesAfterParse.substr(menuNamesAfterParse.find_first_of('|'));        
            menuNamesAfterParse = menuNamesAfterParse.substr(1);
        }
    }

The array size need to be a compile time constant. If you want the size of the array to be decided at runtime you can allocate the array with new or use std::vector.
