Help with destructor

In the following program

Code:

#include<iostream>
using namespace std;
void MyExit(void)
{
	cout<<endl<<"Exit from function!"<<endl;
	exit(0);
}
class MyClass
{
	public:
	MyClass(void)
	{
		cout<<endl<<"Object initialized!";
	}
	~MyClass()
	{
		cout<<endl<<"Object destoryed!"<<endl;
	}
};
int main()
{
	MyClass C1;
	MyExit();
	return 0;
}

The destructor is not executing. What is the reason?
Although I am not terminating the program in main() but still on termination C! should go out of scope which means that the dertructor should run. But it is not happening. Why?

You're terminating the program before the variable's scope ends. The scope lasts until main returns.
If you wanted it to be destroyed earlier then you'd need to insert an additional scope:

Code:

int main()
{
	{
		MyClass C1;
	}
	MyExit();
	return 0;
}

To be more specific, calling exit() "terminates the program without leaving the current block and hence without destroying objects of automatic storage duration" (that is a direct quote from the C++ standard, Section 3.6.1, para 4). C1 is an object of automatic storage duration. For struct/class types, the destructor is invoked during the process of destroying an object.

Avoid using exit. In C, it might be justified, but in C++, as you see, it can cause all sorts of problems.
Always let main go out of scope.

Well if I want to run destructor at every point I terminate the program. What should I do. I may be using this exit() at more than one point.

Don't use exit. Use exceptions instead to signal an error and (possibly) catch it in main.

Well I will post my actual program were I need to do this.

very soon

Read Elysia's last post again. Apart the advice not to call exit(), there is also a suggestion of what you can do instead. No need to post code where you consider you need to call exit().
