Professor Brailsford explains how pointers to pointers can simplify code when working with linked lists.
The 'magic' trick of pointers to pointers - Professor Brailsford explains how what might seem complicated will actually simplify your code. (See Extra Bits video for a code walkthrough) The Professor's Code: bit.ly/Computerphile_ProfBrails_TripleRef EXTRA BITS - Triple Ref Code: youtu.be/1s0w_p5HEuY n.b. Message from the Prof: Many thanks to all of you who have pointed out that I got over excited at the end of this video and (on the LEGO model) did the pointer reassignment in the wrong order. The correct way ( in the model once again) was to do the short pointer first and the longer pointer second - which I think is done correctly in the downloadable C program. facebook.com/computerphile twitter.com/computer_phile This video was filmed and edited by Sean Riley. Computer Science at the University of Nottingham: bit.ly/nottscomputer Computerphile is a sister project to Brady Haran's Numberphile. More at bradyharan.comWhat people say. Recommended as an excellent explanation of pointers-to-pointers and dynamic memory in C.
