n00b question... deleting an object

how do you delete an object once you create it?

With what's called a destructor. Your compiler automatically supplies a default destructor if you don't define one, and a destructor is automatically called when your object goes out of scope, like when your program ends.

Try this code:

Code:

---

include <iostream>
using namespace std;

class MyClass
{
public:
    MyClass() //Constructor
    {
        cout<<"Constructor called."<<endl;
    }

    ~MyClass() //Destructor
    {
        cout<<"Destructor called."<<endl;
    }

    int number;
};


int main()
{
        MyClass an_array[5];
       
        cout<<"In main()."<<endl;

        return 0;
       
}

how do u actually delete the object?

is it anything like
delete <object name>;
free <object name>;
???

Hi,

I was editing my post to address that question specifically. Try re-reading it to see if it explains it now.

thanks for the quick responce, but i was wondering if there was a manual way of deleting it. its not THAT big of a deal, but i have a class just for creating a gui on screen, so once thats one, i just wana have it deleted instead of it hanging around in memory

i COULD call it in another function, but i dont wanna have to write another function specifically just for one object.

Code:

---


MyClass *myclass = new MyClass;
MyClass *myclassarr = new MyClass[10];


delete myclass;
delete[] myclassarr;

Use the delete keyword to free an object. You must pass a pointer to it just as with free(). When deleting an array, use delete[].

thanks!
