Not implemented[edit]
These are currently not implemented in C++. Please implement some if you can. If any tasks are not possible or too complex in C++, they should not be on this list. To mark a task as such, add {{omit from|C++}}, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

Draft tasks without implementation[edit]
These tasks are drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in C++ (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

Requiring Attention[edit]
Examples[edit]
These tasks have implementations in C++, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.
Other pages[edit]
These are other pages related to C++ which require attention; with your knowledge and assistance, we can improve the quality of the site's content.
Not Considered[edit]
These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that C++ was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.
P
R
End of List[edit]
Again, feel free to try your hand at any of the tasks listed on this page.
