classes stuck. can't move forward. Help!

[koopey]

HI. I am beginner in classes. how to work with dynamic memory in classes. I am not able to allocate dynamic array simply in public or private field. so instead allocated the dynamic array in a constructor. but how to access it later either int main() or some other methods of classes like get function to get number stored in that index. eg:

class vectorofint
{
  public:
  vectorofint();
  int set(int index);

private:

};  

vectorofint::vectorofint()

{
    int *array=new int[32];
}

int vectorofint::set(int index)
{
    array[index]=8;///says array is out of scope. how to access the array???
}

Try this delete int at line 14, and declare int*array as member of class

well, doing what u suggested, it didn't show any error. but now while using set function, it gives error: "expected unqualified id before '.' token".

what i did

class vectorofint
{
  public:
  vectorofint();
  int get(int index);
  void set(int index);





  private:
  int *array;



};


void vectorofint::set(int index)
{
    array[index]=8;
}

vectorofint::vectorofint()

{
    int *array=new int[32];
    

}

int main()
{
    class a;
        a.set(8);///gives error at this line

}

Line 36 use vectorofint a; not class a;

[koopey]

well, again solved the problem but again "program not responding". is there any memory leak?

[LendraDwi]

Line 29 you havent delete int*

[koopey]

is it necessary to delete it? just a little bit of memory dynamically allocated. don't see why it should run out of memory.
also even if i delete it using a destructor, still doesn't solve the problem. destructor used:

vectorofint::~vectorofint()
{
    delete array;
}

still same "program not responding".

[LendraDwi]

I mean remove int* from line 29 because *array is already declared

You should have seen me smile right now. it worked! thnx a loooooot.
