is there implementation for b_tree indexing in file structure and organization in c++?

Question

For Example, Consider the following Insertions: Insert: 3, 12
Insert: 7, 24 Insert: 10, 48 Insert: 24, 60 Insert: 14, 72

The index file should look as follow: -1 2 -1 -1 -1 -1 -1 -1 -1 -1 -1 0 3 12 7 24 10 48 14 72 24 60 -1 3 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 4 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

After the previous insertions, Node 1 is a leaf node and all the references in it are pointing to records on data file.

Consider the following Insertion:

The index file should look as follow: -1 4 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 10 2 24 3 -1 -1 -1 -1 -1 -1 0 3 12 7 24 10 48 -1 -1 -1 -1 0 14 72 19 84 24 60 -1 -1 -1 -1 -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

After the previous insertions, Node 1 is a non-leaf node and all the references in it are pointing to other nodes on the index file. Consider the following Insertions: Insert: 30, 96
Insert: 15, 108 Insert: 1, 120

The index file should look as follow: -1 4 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 10 2 30 3 -1 -1 -1 -1 -1 -1 0 1 120 3 12 5 132 7 24 10 48 0 14 72 15 108 19 84 24 60 30 196 -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

Consider the following Insertion:

The index file should look as follow: -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 3 2 10 4 30 3 -1 -1 -1 -1 0 1 120 2 144 3 12 -1 -1 -1 -1 0 14 72 15 108 19 84 24 60 30 196 0 5 132 7 24 10 48 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
