題目：設計稱為car的結構，記錄有關汽車的下列資訊：其製造商存在字元陣鬥的字串中，以及製造的年份，為一整數。寫一程式，先詢問使用者有多少汽車要列進目錄，然後用new配置此數量之car結構的動態陣列。再來，提示使用者輸入每一輛車的製造商(可能由一個以上的單字組成)和製造年份。注意，它要交互讀入字串和數字。最後，顯示每一輛汽車的資訊。程式的幸後結果有如下述：
How many cars do you wish to catalog? 2
Car #1:
Please enter the make: Hudson Hornet
Please enter the year made: 1952
Car #2:
Please enter the make: Kaiser
Please enter the year made: 1951
Hereis your collection:
1952 Hudson Hornet
1951 Kaiser
紅色的字為輸入。

以下兩個程式碼都是用指標做的，但方法有點小差異。
程式碼一：
/*damody
car question
I like*/
//7/17
#include <iostream>
#include <cstring>
using namespace std;
struct car // structure declaration
{
char * name;
int year;
};
char * getname()
{
char temp[80];
cin.get(temp、80);
char * pn = new char[strlen(temp) + 1];
strcpy(pn、temp);
return pn;
}
int main()
{
int Num;
cout << "How many cars do you wish to catalog? ";
cin >> Num;
cin.get();
car * inf = new car + Num;
for (int i = 0;i < Num;i++)
{
cout << "Car #" << i + 1 << ":" << endl;
cout << "Please enter the make: ";
cin.get(inf -> name,20);
cin.get();
cout << "Please enter the made: ";
cin >> (*inf).year;
cin.get();
*inf++;
}
cout << "Here is your collection:\n";
inf -= Num;
for (int i = 0;i < Num;i++)
{
cout << inf[i].year << " " << inf[i].name << endl;
}
delete inf;
return 0;
}
