c++简单问题，代码清晰，求解！

Question

分别用char数组和string类型编写代码，使他们输出相同。

#include<iostream>
#include<string>
int main()
{
    using namespace std;
    string name;
    string dessert;

    cout << "Enter your name:\n";
    getline(cin,name);
    cout << "Enter your favorite desseert:\n";
    getline(cin,dessert);
    cout << "I have some delicious " << dessert;
    cout << " for you," << name << ".\n";
    return 0;
}

#include<iostream>
#include<string>
int main()
{
    using namespace std;
    const int AirSize = 20;
    char name[AirSize];
    char dessert[AirSize];

    cout << "Enter your name:\n";
    cin.getline(name,AirSize);
    cout << "Enter your favorite desseert:\n";
    cin.getline(dessert,AirSize);
    cout << "I have some delicious " << dessert;
    cout << " for you," << name << ".\n";
    return 0;
}

哪里不对，麻烦指出.谢谢

 #include<iostream>
#include<string>
int main()
{
    using namespace std;
    string name;
    name.resize(20);
    string dessert;
    dessert.resize(20);
    cout << "Enter your name:\n";
    cin.getline((char *)name.c_str(), 20);
    cout << "Enter your favorite desseert:\n";
    cin.getline((char *)dessert.c_str(), 20);
    cout << "I have some delicious " << dessert;
    cout << " for you," << name << ".\n";
    return 0;
}
