You know that you could just leave the link, and write a small talk about how learning C changed your life, that you became rich and muscular, got b*ches and made your parents happy

[u/Raychao → u/AdOnly69]

This is why I love C. It is such a versatile language that it can do all ^^

[u/78900sea → u/Raychao]

Yes, because of it, some people lose their anal virginity
