摘要

TLDRThe time required to learn C++ varies significantly depending on one's prior programming knowledge and objectives. For those who already know programming in multiple languages, basic C++ can be learned in a few days to weeks by reading guides such as 'A Tour of C++' and practicing with different libraries. However, for complete novices, acquiring a professional level in C++ may span several months or even years due to the necessity of understanding fundamental computing concepts as well. The analogy used compares learning C++ to mastering a musical instrument: if nobody's listening, or if only personal satisfaction is required, it might take less time. However, achieving a level suitable for high professional standards requires more years of study. Overall, the time dedicated to learning should reflect one's targeted competency and understanding of related computer science areas.

    how long does it take to learn
  • 00:00:11
    C++
  • 00:00:12
    depends what you want to do and what you
  • 00:00:15
    already
  • 00:00:16
    know um if you are already a programmer
  • 00:00:21
    in quite a few
  • 00:00:23
    languages um my recommendation is to
  • 00:00:26
    read the tour of C++ second edition you
  • 00:00:29
    can do it in the weekend and now you
  • 00:00:32
    have the fundamentals and you have to do
  • 00:00:34
    some experimentation and probably dig
  • 00:00:36
    deeper into the areas your interested in
  • 00:00:38
    if you want to do anything you have to
  • 00:00:40
    pick up some libraries and learn them
  • 00:00:43
    but we're talking days or weeks but that
  • 00:00:47
    assumes your a programmer if I have to
  • 00:00:49
    explain to you what a link list is or
  • 00:00:51
    what a vector is or what a hash table is
  • 00:00:53
    uh then it takes much longer so if you
  • 00:00:56
    start from the beginning to reach the
  • 00:00:59
    professional level
  • 00:01:01
    we're talking months and
  • 00:01:03
    years um and and and one question I
  • 00:01:06
    sometime ask is how long does it take to
  • 00:01:08
    play a violin to learn to play a violin
  • 00:01:12
    well if nobody's listening it's easy if
  • 00:01:15
    only your mother has to appreciate it uh
  • 00:01:18
    maybe it'll do fine um but otherwise
  • 00:01:21
    it'll take years now if you're already a
  • 00:01:25
    violinist and you want to play a viola
  • 00:01:27
    you can probably do it in a couple of
  • 00:01:29
    weeks depends what you are uh what your
  • 00:01:33
    background is what you already knows and
  • 00:01:35
    then how good do you want to be at it if
  • 00:01:39
    if you're if you're thinking about uh
  • 00:01:41
    the Lincoln Center you better spend
  • 00:01:43
    years and the equivalent for uh a
  • 00:01:46
    programming language if you want to be
  • 00:01:48
    the ace programmer uh building the Next
  • 00:01:51
    Generation infrastructure or the next uh
  • 00:01:54
    absolutely great um uh sort of
  • 00:01:58
    application you better spend some Years
  • 00:02:01
    Learning not just the programming
  • 00:02:03
    language but your basic computer science
  • 00:02:06
    and your application areas
