问题描述:

1.包装一个可扩展的动态的两维数组,支持泛型;

2.把存取的细节都包装起来,留一些简单的接口供外部使用;

3.稍作扩展可代替STL vector 使用;


程序代码:

#ifndef _TWODIM_ARRAY_H_
#define _TWODIM_ARRAY_H_

#include 
#include 

/*
* encapsulate two dimension array 
*
*/
template
class TwoDimArray
{
public:
	TwoDimArray():m_storage(0), m_row(ROW), m_col(COL),
		          m_curRow(0), m_totalCount(0)

	{

	}

	/*
	*Copy constructor
	*
	*/
	template
	TwoDimArray( const TwoDimArray& rhs ):m_storage(0), m_row(ROW), m_col(COL),
													   m_curRow(0), m_totalCount(0)
	{
		for( size_t i = 0; i 
	TwoDimArray& operator = ( const TwoDimArray& rhs )
	{
		if( this != &rhs )
		{
			Clear();

			for( size_t i = 0; i  0 );
		return (*this)[idx - 1];
	}

	/*
	*
	*
	*/
	T& Next( size_t idx )
	{
		assert( idx  0 );
		return (*this)[idx - 1];
	}

	/*
	*
	*
	*/
	const T& Next( size_t idx ) const 
	{
		assert( idx  m_curRow )
		{
			m_curRow++;
			m_storage[m_curRow] = new T[m_col];
			memset( m_storage[m_curRow], 0x00, sizeof(T) * m_col );

			return &m_storage[m_curRow][0];
		}
		else
		{
			return &m_storage[curRow][m_totalCount % m_col];
		}
	}

private:
	T**    m_storage;
	size_t m_col;
	size_t m_row;
	size_t m_curRow;
	size_t m_totalCount;

	
};

/*
*Test interface
*
*/
void TestTwoDimArray()
{
	TwoDimArray dimArr;

	int len = 6 * 6;
	for( int i = 0; i  newdimArr(dimArr);
	assert( newdimArr.Size() == dimArr.Size() );
	for( int i = 0; i
