Hi, I am attaching error and the code which caused this error. Can any body help?

Code
Code:
#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

class CMyClass
{
	int m_nInt;
public :
	CMyClass()
	{
		m_nInt = 0;
	}

	CMyClass(const int nInt)
	{
		m_nInt = nInt;
	}

	CMyClass(const CMyClass& rMyClass)
	{
		m_nInt = rMyClass.m_nInt;
	}

	bool operator = (const CMyClass& rMyClass)
	{
		return (m_nInt == rMyClass.m_nInt);
	}

	bool operator > (const CMyClass& rMyClass)
	{
		return (m_nInt > rMyClass.m_nInt);
	}

	bool operator < (const CMyClass& rMyClass)
	{
		return (m_nInt < rMyClass.m_nInt);
	}

	bool operator = (const int nInt)
	{
		return (m_nInt == nInt);
	}

	bool operator > (const int nInt)
	{
		return (m_nInt > nInt);
	}

	bool operator < (const int nInt)
	{
		return (m_nInt < nInt);
	}
};

typedef vector<CMyClass> CMyClassVec;
int main()
{
	CMyClassVec v;
	CMyClass c1(20),c2(5),c3(50),c4(2),c5(50);
	v.push_back(10);
	v.push_back(c1);
	v.push_back(100);
	v.push_back(c2);
	v.push_back(c3);
	v.push_back(c4);
	v.push_back(c5);


	int quantity = 0;

	quantity = count(v.begin(),v.end(),c2);
	cout << "object equal to c2 = " << quantity << endl;
	cout << endl;
	return 0;
}
