Basic array of classes

[spirou]

Hi, i'm a bit lost by using C++.

I want to store the adresses of each instances of a classe in an array of pointers.

Here is a sample of what i'm trying to do :

class object{
 ...
};

main()
{
  object **a_objects;
  a_objects = new (* objet)[10];

  objet myobject1();
  a_objects[0] = &myobjet1;

  objet myobject2();
  a_objects[1] = &myobjet2;

  ...
}

This syntax doesn't work, he he it's a bit painful but I'm a noob

May someone help me ?


P.s: I hope that there are not too much mistakes in my english. (poor french)

a_objects = new (* objet)[10];
a_objects = new object* [10];

hmmm,

another pb :

class object{
 fct1(){...};
};

main()
{
  object **a_objects;
  a_objects = new objet*[10];

  for( int i; i<10; i++) a_objects[i]=NULL;
  ...
  for( int i; i<10; i++){
    if(

a_objects[i] != NULL

 ) /* acces violation ? */
      a_objects[i]->fct1();
  }
  ...
}

Sorry sometime I'm a bit stupid.

This code works.

Well actually you do have a problem. You need to initiailize the "i" variable in your for loops or it could be anything, for example -200, which might indeed cause an access violation.

for(int i=0; ....)

Always initialize variables... ALWAYS.
