Can we make a bookmark or something in a file ?

so it can start reading or writing it from there

one file but divided into parts which can be easily read,write,delete or modify.

Harder version:
Keep records of line numbers and seek to those points each time you want to reach it.

Easier version:
Use a database.

little forgot ............out of touch

some like class in c++ and struct in c

but to confirm.........

Simple version - use objects(of structure or class) to store data.
Harder version - read the pointer position where you want your "bookmark" to be and store it somewhere. Use seekg to navigate there.

simple way -

harder -

read the file upto where you want the bookmark. use tellg and store the return value somewhere. when you want to go back to bookmark, use seekg(saved value)
