Destructor Question

[Leslie]

I wanted to create a little program to demonstrate constructors and destructors to some students. I am using Dev C++ v.4.9.9.2

The code looked like this:

include <iostream>

using namespace std;

class Truck
{
public:
Truck();
~Truck();
};

Truck::Truck()
{
cout<<"The Truck constructor has run"<<endl;
}
Truck::~Truck()
{
cout<<"The Truck destructor has run"<<endl;
}

int main()
{
Truck TwoTon;
cout<<"This program demonstrates an object with \n";
cout<<"a constructor and a destructor"<<endl;
system("pause");
return 0;
}

The code is pretty straight forward, and it does compile; however, the destructor message never appears. The first two messages do appear in the appropriate order. I was wondering if anyone else had experienced this problem. The point was to demonstrate the order in which the methods/output statements execute.

Thanks in advance,
Leslie

Ok, great, thanks. I was wondering if it was actually called before or after the system ("pause");

I tried putting the code in its own code block, as suggested, with the system("pause"); on the outside and it worked like a charm.

Thanks so much!

Old post I know,
but try this...

int main()
{
{
Truck TwoTon;
cout<<"This program demonstrates an object with \n";
cout<<"a constructor and a destructor"<<endl;
}
system("pause");
return 0;
}

TwoTon's destructor should be called when it leaves it's scope,
before the destructor wasn't called until after the system("pause") command.

thanks in advice
