c++ - Is this how I should be understanding what a multiway tree is? -

i implement multi-way tree in c++, still not sure are. have read few documentations, still confused because of lack of pictures or visualization provided.

lets want 3 way tree, according online web notes means each node can have @ 3-1 = 2 elements , each node can have @ 3 children. below have drawn trees not sure if 3-way trees, can please verify understanding correctly? thank you!

also, if have 2 way tree, mean have binary tree well? o.o?

my understanding of multi-way tree number of subtrees can traversed single node.

           +---+              | d |            +---+                ^                |                |   +---+     +------+     +---+   | | <-- | root | --> | b |   +---+     +------+     +---+              |                |                v            +---+              | c |              +---+   

the diagram above shows multi-way tree because root has more 1 child.

usually 2 children per node (except leaf nodes) indicates binary trees.
there many different kinds of binary trees.

see b-tree , b*trees.
