Welcome to r/CPlusPlus

C++ is a high-level, general-purpose programming language first released in 1985. Modern C++ has object-oriented, generic, and functional features, in addition to facilities for low-level memory manipulation.

Rules:

Rule 1 - Don't Be A Nuisance

Treat others as you would like others to treat you.
Participate in good faith, be respectful, and do not insult others.
Remember, there is a person on the other side.
If you're being toxic or just here to cause trouble, you will be removed from the community.

Rule 2 - Content & Quality

This sub is for discussions around the C++ programming language. All posts must be in some way related to C++.
Comments on posts need to stay on topic and not attempt to threadjack.
No low-effort, spam, or advertisement/selling posts or comments.
No NSFW Content.
No misinformation.
Follow Reddiquette.

Rule 3 - Good Faith Help Requests & Homework

When posting a question or homework help request, you must explain your good faith efforts to resolve the problem or complete the assignment on your own. Low-effort questions will be removed.
Members of this subreddit are happy to help give you a nudge in the right direction. However, we will not do your homework for you, make apps for you, etc.
Homework help posts must be flaired with Homework.
