Nodes are structures that contain data and also can point and “link” to another node, creating a list.

Nodes do not necessarily need to be a named variable, but rather can be pointed to by variables that can be moved depending if the list has been changed.(ie. start&tmp)

Ternary statements= “(condition) ? statementiftrue : statementiffalse;”

“List” in sll0 is just an “engine” and “caboose”, which are pointers (like tmp) to “start” and “end”, therefore “mklist()” is merely allocating memory for the pointers to start and end
