Sir for part D, the program I coded shows the empty nodes aswell which I believe is because printAll( ) loops 20 times but your output only shows the 10 times inputted even though I coded the exact same thing. Is that a problem or just an updated VB as this video is 2 years old?

Hi, in the procedure AddNode, why we should not declare the parameters as integer? Like for example byref ArrayNodes, why should we not declare it like that: 'byref ArrayNodes(, ) as integer? Can you please enlighten me please?
