关于 char* xxx[] 的使用,该如何处理

#include <cstring>
#include <iostream>

using namespace std;

int ConstStringCopy(char* NewStringList[], const char* ConstStringList[], const int& lines)
{
    int i = 0;
    
    for (; i<lines; ++i)
    {
        NewStringList[i] = NULL;
        NewStringList[i] = new char(strlen(ConstStringList[i]) + 1);
        strncpy(NewStringList[i], ConstStringList[i], strlen(ConstStringList[i])+1);
    }
    
    return i;
}

void DestroyCopy(char* NewStringList[], const int& lines)
{
    int i = 0;

    while ((NULL!=NewStringList[i]) && (i<lines))
    {
        delete[] NewStringList[i];
        NewStringList[i] = NULL;
        ++i;
    }
}

int main ()
{
    const char* string_a[1] = {"This is a long text line. This is a const string convertion utility."};
    const char* string_b[2] = {"AAA", "BBB"};
    
    char* newstring_a[1];
    char* newstring_b[2];
    
    ConstStringCopy(newstring_a, string_a, 1);
    ConstStringCopy(newstring_b, string_b, 2);
    
    cout << newstring_a[0] << endl;
    cout << newstring_b[0] << endl;
    cout << newstring_b[1] << endl;

    // DestroyCopy(newstring_a, 1);
    // DestroyCopy(newstring_b, 2);
    
    return 0;
}
