最近在学习C++ Primer Plus这本书，里面第四章讲到了指针分配内存，课后有一道练习题： 结构CandyBar包含三个成员：糖块的品牌，糖块的重量（可以有小数），糖块的卡路里含量（整数），编写一个程序，使用new来动态分配一个包含三个元素的CandyBar数组，并将他们初始化为所选择的值，然后显示每个结构的内容。下面是我的代码，总是从16行开始出错，希望各位高手赐教。。因为刚学C++不久。。比较菜。。。见笑了。。 //ex6.cpp The exercise 6 in 4.10 of C++ Primer Plus //2005-10-22, WizCas

#include <iostream>

using namespace std;

struct CandyBar { char name[20]; double weight; int ka; };

int main () { CandyBar * snack = new CandyBar [3]; snack[0] = {"ABC", 1, 2}; snack[1] = {"DEF", 3, 4}; snack[2] = {"GHI", 5, 6}; int i;

for (i=0; i<=2; i++) { cout << "The name of the CandyBar is " << snack[i]->name << ".\n" << "The weight of the CandyBar is " << snack[i]->weight << " g.\n" << "The #$%#$% of the CandyBar is " << snack[i]->ka << " @#$.\n" << "=================================\n"; } delete [] snack; system("pause"); return 0; }

#include <iostream>

using namespace std;

struct CandyBar { char name[20]; double weight; int ka; };

int main () { CandyBar * snack=new CandyBar [3]; snack[0]=("ABC", 1, 2); snack[1]=("DEF", 3, 4); snack[2]=("GHI", 5, 6);

int i;

for (i=0; i<=2; i++) { cout << "The name of the CandyBar is " << snack[i].name << ".\n" << "The weight of the CandyBar is " << snack[i].weight << " g.\n" << "The #$%#$% of the CandyBar is " << snack[i].ka << " @#$.\n" << "=================================\n"; } delete [] snack; system("pause"); return 0; }

还有三个错误，望有识之士指教

自己顶一下。。高手们帮忙解答一下可以吗？。。因为第五章的练习题也有这方面的内容。。就是指针结构数组如何赋值。。

再顶..很急...各位高手帮下忙好吗..在线等了一天了..=0=

#include &lt;iostream&gt;

#include &lt;cstdlib&gt;

using namespace std;



struct CandyBar

{

    char name[20];

    double weight;

    int ka;

};



int main ()

{

  CandyBar * snack = new CandyBar [3];

    CandyBar temp1 =  {"ABC", 1, 2};

  CandyBar temp2 =  {"DEF", 3, 4};

    CandyBar temp3 =  {"GHI", 5, 6};

  snack[0] = temp1;

    snack[1] = temp2;

  snack[2] = temp3;



  int i;



  for (i=0; i&lt;=2; i++)

  {

    cout &lt;&lt; "The name of the CandyBar is " &lt;&lt; snack[i].name &lt;&lt; ".\n"

         &lt;&lt; "The weight
of the CandyBar is " &lt;&lt; snack[i].weight &lt;&lt; " g.\n"

         &lt;&lt; "The #$%#$%
of the CandyBar is " &lt;&lt; snack[i].ka &lt;&lt; " @#$.\n"

         &lt;&lt; "=================================\n";

  }

  delete [] snack;

  system("pause");

  return 0;

}

啊老大终于出来了!恩谢谢!!

你定义一个构造函数就可以了啊。
C++和C 的语法要求有点差别啊！

谢谢大家!!感激!
