请你给出我所有函数的代码和主函数的代码

好的，以下是 DynamicArray 类模板的成员函数和菜单程序的代码示例：

#include <iostream>
#include <cstring>
#include <algorithm>

using namespace std;

template <typename T>
class DynamicArray
{
private:
    int m_length; // 数组长度
    int m_count;  // 元素个数
    T* m_data;    // 数据指针

public:
    // 构造函数和析构函数
    DynamicArray()
    {
        m_length = 10;
        m_count = 0;
        m_data = new T[m_length];
    }

    ~DynamicArray()
    {
        delete[] m_data;
    }

    // 添加元素
    void AddItems(T aData[], int aLen)
    {
        if (m_count + aLen > m_length)
        {
            T* newData = new T[m_length + aLen];
            memcpy(newData, m_data, m_count * sizeof(T));
            delete[] m_data;
            m_data = newData;
            m_length = m_length + aLen;
        }

        memcpy(m_data + m_count, aData, aLen * sizeof(T));
        m_count = m_count + aLen;
    }

    // 删除元素
    bool RemoveAt(int index)
    {
        if (index < 0 || index >= m_count)
        {
            return false;
        }

        if (index == m_count - 1)
        {
            m_count--;
            return true;
        }

        for (int i = index; i < m_count - 1; i++)
        {
            m_data[i] = m_data[i + 1];
        }

        m_count--;
        return true;
    }

    // 插入元素
    void InsertItem(int index, T aData)
    {
        if (index < 0)
        {
            index = 0;
        }

        if (index > m_count)
        {
            index = m_count;
        }

        if (m_count == m_length)
        {
            T* newData = new T[m_length * 2];
            memcpy(newData, m_data, m_count * sizeof(T));
            delete[] m_data;
            m_data = newData;
            m_length = m_length * 2;
        }

        for (int i = m_count; i > index; i--)
        {
            m_data[i] = m_data[i - 1];
        }

        m_data[index] = aData;
        m_count++;
    }

    // 数组排序
    void mySort()
    {
        sort(m_data, m_data + m_count);
    }

    // 其它功能
    // ...

    // 获取元素个数
    int getCount()
    {
        return m_count;
    }

    // 获取数组长度

    // 获取数据指针
