Exception propagation is the process by which an exception is passed up the call stack until it is caught by an appropriate exception handler. This mechanism allows for centralized error handling and helps maintain code readability by separating normal logic from error handling logic.

A call stack is a data structure used by programming languages to keep track of function calls and manage execution context. It operates on a Last In, First Out (LIFO) principle, enabling the program to return control to the correct location after a function completes execution.

Code readability refers to how easily a human reader can understand and navigate through the source code of a program. It is crucial for maintaining, debugging, and extending software, as well as for facilitating collaboration among developers.
