How does a buffer overflow happen?

It typically happens when a program writes more data to a buffer than it can hold, often due to improper input validation.

What are the consequences of a buffer overflow?

Consequences can include crashes, data corruption, and exploitation by attackers to execute arbitrary code.

How can I prevent buffer overflow in my code?

You can prevent buffer overflows by using safe functions, validating input sizes, and employing modern programming languages that handle memory management.
