Student asking too many questions without trying themself

Establish clear learning goals that include problem solving and finding the answers as part of the task.

This essentially falls under the "teach someone to fish" adage. The most important skill to learn in a programming boot camp isn't going to be a repertoire of functions or a mastery of a certain language's syntax, but rather a piece of the programming process itself, which includes problem solving and the associated skills.

It sounds like you're getting broken down by complaints and feeling like you have to provide an answer to help with a given line of code, but I think if you instead frame it in your own mind (and make clear to the students as well) that you are teaching the entire process, it will be easier to refuse to answer those questions and refocus on ways that the student can find their own answer.
