how to add copy contructor to this class since the construtor has a void

class Utils {

public:

// Constructor
Utils(void);

// copy Constructor
Utils(const Utils &src);

// Destructor
~Utils(void);

// This method will write two bytes to given destination
void writeTwoBytes(usigned char *desPtr, unsigned short src);

// This method will read two bytes from a given source pointer
ubin16 readTwoBytes(unsigned char *srcPtr);

// This method checks the range
ubin8 rangeCheckingPorts(PTypes eType, unsigned short sourceIpPort,
unsigned short destIpPort);

private:

// This method checks for big endian at run time
int isBigEndian();

// This member variable stores the output of the isBigEndian
int m_bigEndianTest;

};
