/*      date:5th january 2011     programmer:fahad */ #include <iostream> #include <string> using namespace std; class persons //a class store name,addresses , id numbers of users {     private:         string name_;         string address_;         int id_number_;      public:         static int count;//this count of objects created         persons();         void getdata(int n);         void displaydata(int n);         //~persons(); }; static int count;//initializing static member int main() {     cout << "enter number of persons:";     int n;//this number of objects user wants make.     cin >> n;     persons *ptr;//a pointer used dynamic memory allocation.      /*exception handling*/     ////////////////////////////////////////////////////////////////////     try     {         //ptr=new [sizeof(persons) * n];         ptr=new persons[n];     }     catch(bad_alloc xa)     {         cout<<"sorry,program can not continue";         cin.get();         exit(1);     }     /////////////////////////////////////////////////////////////////////     for(int = 0; i< n; i++)     {         ptr[i].getdata(n);     }     for(int j = 0; j< n; j++)     {         ptr[j].displaydata( n );     }     cin.get();     delete[] ptr;     return 0; } /*function definitions*/ persons::persons() {     name_="";     address_="";     id_number_=0;     count++; } void persons::getdata(int n) {          cout<<"enter name (press '$' exit):";         getline(cin,name_,'$');         cout<<endl<<"enter address (press '$' exit):";         getline(cin,address_,'$');         cout<<endl<<"enter identitiy card number:";         cin>>id_number_;  } void persons::displaydata(int n) {          cout<<"name:"<<name_;         cout<<endl<<"address:"<<address_;         cout<<endl<<"identitiy card number:"<<id_number_;  }

error:

------ build started: project: new, configuration: debug win32 ------ compiling... program.cpp c:\documents , settings\1\my documents\visual studio 2008\projects\new\new\program.cpp(23) : error c4430: missing type specifier - int assumed. note: c++ not support default-int build log saved @ "file://c:\documents , settings\1\my documents\visual studio 2008\projects\new\new\debug\buildlog.htm" new - 1 error(s), 0 warning(s) ========== build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== ?

instead of

static int count;//initializing static member

write

int persons::count;

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (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."
