beauty of programming

These days finally I've got time to exercise English typing as well as to read something.I've just started to programme so some of  my perspectives remain naive so I reeeeeally appreciate those who would tick out my mistakes.

The pre-chapters told me many things about the research position and some useful experiences during the interview,but as time goes by I forgot them and only a few lines remained in my mind: 

A> How to allocate your time under great pressure in a wise way is pretty important,cause programmers never got sufficient time to finish those projects.

B>You're supposed to get PREPARED for the interview you're going to take.Like how much do you know about the company, the position you're requiring,and so on.(There was an exampleNEW WAVE,which is an example of picking up things unexpectedly)

1.1 the first time I totally could not understand this at all.\

1.2 the condition is a little bit critical,but the answer amazed me while it used the binary operations and macros,which is preetty new and interesting to me.Afterwards I met the second and the third way of solving problems,and the second sounds more of my dish,while the third one expanded the imagination by taking a structure as a variable,which is nice.
