How to Ask a Programming Question

Anyone can ask a question in our programming channels. Following the guide Writing The Perfect Question is recommended.

What to Post

State your problem clearly and provide all necessary details:

  • the relevant portion of your code, or all of it
  • the expected output
  • the actual output (or the full error)
    :trophy: Gold Standard: Minimal Reproducible Example
Where to Post

Provide the relevant code in the message, and format it nicely with a code block*. If it's too much for one message, you can upload it:

  • Compiler Explorer for most C and C++ snippets
  • OnlineGDB for interaction, debugging
    :no_entry: Do not post screenshots, let alone photos of your screen!
* Use /code if you don't know how to format code blocks

Why Should I Format My Code, and How Do I Do It?

Well-formatted code is much easier to read, especially for people who haven't written it themselves. Poor formatting can even be misleading, especially indentation:

while (is_waiting);    // BAD! reader may think that
  std::cout << "hi\n"; // printing is in the loop

while (is_waiting) { } // good, empty statement
std::cout << "hi\n";   // is clearly visible
Rules for Code Formatting
  1. Stay consistent! (much easier when using auto-formatters)
  2. Don't use exotic styles that surprise readers.
  3. The rest is up to personal preference.
Auto-Formatting with clang-format

For C and C++, you can use clang-format to decide on a style, and apply it automatically to your files. You can use it in the terminal, or through an editor plugin.

Most IDEs will also let you configure a style in their settings, but clang-format is universal.
