How can I fix a buffer overflow in my code?

Buffer overflows occur when data exceeds the allocated memory. You can fix it by checking array bounds and using safer functions.

What are some common causes of buffer overflow?

Common causes include improper input validation, using unsafe functions like gets(), and not allocating enough memory.

Can you give me an example of how to prevent it?

Sure! Instead of using strcpy, use strncpy to limit the number of characters copied to the buffer.

Are there tools to help detect buffer overflows?

Yes, tools like Valgrind, AddressSanitizer, and static analysis tools can help detect buffer overflows.
