What distinguishes a framework from a library in software development?

The main difference between a framework and a library lies in the control over the program's flow:

• Library — a set of ready-made functions or classes that the developer calls at their discretion. Control over the program remains with the developer.

• Framework — the application skeleton that defines the structure and flow of execution. The developer writes code that is called by the framework (the principle of "inversion of control").

Example: when using a library, you call its methods yourself, but when using a framework, your code is called by it at the appropriate moment.
