calling ctor inside a member function of a class

Hello. May I ask a question to the ctor in this program.

main.cpp:

Code:

#include <iostream>
#include "cTest.h"

int main()
{ 
	cTest i;

	i.SetA(5);

	i.ClearA();

	return 0;
}

cTest.h:

Code:

#pragma once

class cTest
{
public:
	cTest(void)
	{itsA = 0;}
	~cTest(void){}
	void SetA (int i)
	{itsA = i;}
	void ClearA ()
	{cTest();}
private:
	int itsA;
};

I am wondering, why the value of 'itsA' is not '0' after 'i.ClearA();' was called in main.cpp.

Thanks.
F.R.
