Safely Using snprintf: Avoid Buffer Overflows

This article highlights a lesser-known feature of the `snprintf` function: its ability to determine the required buffer size before formatting, thus preventing buffer overflows. By calling `snprintf` twice – once with `NULL` and 0 to get the size, and again with a properly allocated buffer – the need for manual buffer size calculations is eliminated. The author also recommends a lightweight header-only library for easier usage.
