c++ - Can there be two public section in a class? If yes then why ? And in which circumstances we do so? -

-

there bugging me classes. example

class { public:   a()   {   .....   .....   }    void cleanup()   {   ....   ....   ....   }  public:   uint a;   ulong b; };

in above example there 2 public section. in first section defining constructor , method , in second section declaring data members. above class i.e. correct. can that? if yes why needed , in circumstances should use it? since can entire thing in 1 section why there 2 sections?

access qualifiers apply code follows until next qualifier. there no restriction on number or order of such qualifiers.

it not necessary repeat same access qualifier in class, , doing confuse reader. may have effect on layout of class, since data members following same qualifier must laid out in order declared, there no such restriction between qualifiers.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
