Explanation:
- Line 1 to 4: We have created a new structure named Node (we will create Nodes of our linked list using this structure).
- Line 6: Start of the main() function.
- Line 7: We have declared a pointer variable, named: start (Note this pointer variable can only point to things which are type of Node).
- Line 8: We have made "start", a "NULL" (just to make sure that it contains no dummy values).
- Line 9: "new Node" means create a new Node,
and "start = new Node" means "start variable is pointing to the newly created node".
- Line 10: place "10" inside the "data" member of that node, which start is pointing to.
- Line 11: make "link" member of the node "NULL"
- Line 12: just output "data" part of the node, which start is pointing to.
