weird output when using delete

[Skwidman157]

So I get some weird output to the cmd promt when running this.

class Item{
protected:
	unsigned short int m_value;
	string m_name;
	unsigned short int m_type;

public:
	Item(int itemCreating){
        //---NA---
	}
	~Item();
	int getValue(){ return m_value; }
	string getName(){ return m_name; }
	int getType(){ return m_type; }

};

class MeleeWeapon : public Item{
private:
	unsigned short int m_damage;
	unsigned short int m_weaponRef;

public:
	MeleeWeapon(int itemCreating) : Item(itemCreating){
        //---NA---
        }
	
	~MeleeWeapon();
	int getDamage(){ return m_damage; }
};

  int main()
{
	MeleeWeapon * pPipeWrench = new MeleeWeapon(PipeWrench);

	delete pPipeWrench;

	return 0;
}

output says:

'"c:\users\dev\documents\visual studios\Projects\class fun\Debug\classFun.exe"' is not recognized as an internal or external command, operable program or batch file.

------------------------------------------

I don't know if I am properly deallocating pPipeWrench or not. I have googled destructors in c++ many times and to me it looks like I am doing it right.

If I dont use the delete operator the program runs.

any ideas???

Also, after I close the com prompt I get this error:

Error 1 error LNK2019: unresolved external symbol "public: __thiscall MeleeWeapon::~MeleeWeapon(void)" (??1MeleeWeapon@@QAE@XZ) referenced in function "public: void * __thiscall MeleeWeapon::`scalar deleting destructor'(unsigned int)" (??_GMeleeWeapon@@QAEPAXI@Z) c:\Users\development\documents\visual studio 2013\Projects\classFun\classFun\classFun.obj classFun

NVM!

I forgot to include the body for the destructor... smh. its late.

for any one who stumbles upon this later the destructors should look like:

~MeleeWeapon(){};

// NOT like \/\/

~MeleeWeapon(); 

what I was doing was only declaring it and not defining it.

You should initialize the [POD] member variables (m_value/m_type).

If you don't need a destructor you don't need to declare one. However it is wise to have virtual destructor for the base class. Otherwise the destructors of the inherited classes might not be called.
