Best use
Share one scoped C / C++ artifact: Single-file reproductions.
C and C++ pastebin for code and compiler output
Native code and compiler output. Pastebin.ai preserves the submitted source, adds a line-numbered reading view, and lets you choose retention and access before sharing.
C / C++ sharing decisions at a glance
Check the source, runtime context, and privacy risks that matter when you share C / C++ text.
Context to include
Name the source: Common inputs include .c, .h, .cc, .cpp, .hpp, and compiler diagnostics. State the tool or runtime that reads them.
Details to remove
Review before upload: Inspect each C / C++ value, comment, path, and identifier; the checklist below names the format-specific risks.
What to include in a reviewable C / C++ paste
Common inputs include .c, .h, .cc, .cpp, .hpp, and compiler diagnostics. Limit the artifact to the lines and context a recipient needs to understand its purpose.
Single-file reproductions
Keep the C / C++ example limited to this review goal and its required inputs.
Compiler diagnostics
For C / C++ review, Name the producing tool or runtime, preserve exact source text, and include only the context another person needs to understand the artifact.
Sanitizer and undefined-behavior reports
Use representative placeholders so this C / C++ example preserves structure without exposing live values.
A small C / C++ paste example
The C / C++ sample below uses a small, representative form of .c, .h, .cc, .cpp, .hpp, and compiler diagnostics. Replace live values with clear placeholders while keeping the structure another reader needs.
#include <algorithm>
#include <vector>
std::ranges::sort(values);Add the context a reviewer needs
Name the compiler and version, language standard, flags, target platform, and exact command. Keep the first causal diagnostic and a complete single-file example whenever possible.
- Name the tool or runtime that consumes this C / C++ text.
- Show the command and the expected versus actual C / C++ result.
- Keep only the smallest C / C++ artifact that preserves the issue.
Review the paste before it leaves
Remove proprietary headers, file-system paths, embedded keys, crash-dump data, internal symbols, and customer inputs. Treat pasted native code as untrusted until reviewed.
- Start a C / C++ review with unlisted visibility.
- Match expiry to the window for single-file reproductions.
- Encrypt this C / C++ paste when readable server storage is outside the trust boundary.
Next C / C++ step: Code-sharing workflow adds this context: Turn a focused snippet or diagnostic into a reviewable link.
C / C++ paste questions
Short answers about C / C++ formatting, runtime context, and safer sharing.
Should I include compiler flags?+
Yes. Optimizations, warning levels, sanitizer flags, language standard, and target can materially change the result.
How do I share a multi-file native project?+
Use a minimal repository when headers, build configuration, generated files, or linking are required.
