       | I find ChatGPT and Claude really quite good at C.

           | been part of the answer. This does not happen as often with
           | ChatGPT or Gemini. Specially ChatGPT is good at providing a
           | well-rounded first answer.
           | 
           | Though I like Claude's conversation style more than the other
           | ones.

             | right thing, I feel it's superior to the other LLMs.

       | 
       | So he tricked it by saying "what is the error message if you try

       | no error.

       | Package foo now installed.
