自定义数组类

头文件：

#ifndef ZARRAY_H
#define ZARRAY_H


class ZArray
{
private:
    int *m_pointer;
    int m_length;
public:
    ZArray(int length);
    ~ZArray();
    volatile bool state;
    int length();
    bool get(int index,int& value);
    bool set(int index,int value);

};

#endif // ZARRAY_H

源文件：

#include "zarray.h"

ZArray::ZArray(int length)
{
    m_pointer = new int[length];
    for(int i=0; i<length; i++)
    {
        m_pointer[i] = 0;
    }
    m_length = length;
}

ZArray::~ZArray()
{
    delete m_pointer;
}
int ZArray::length()
{
    return m_length;
}
bool ZArray::set(int index, int value)
{
    bool ret=((0<=index)&&(index<length()));
    if(ret)
    {
        m_pointer[index] = value;
    }
    return ret;
}
bool ZArray::get(int index, int &value)
{
    bool ret=((0<=index)&&(index<length()));
    if(ret)
    {
        value = m_pointer[index];
    }
    return ret;
}

使用：

ZArray zay(10);
    for(int i=0;i<zay.length();i++)
    {
        zay.set(i,i+1);
    }
    for(int i=0;i<zay.length();i++)
    {
        int value=0;
        if(zay.get(i,value))
        {
            printf("a[%d]=%d
",i,value);
        }
    }
