定义了一个Iceman类, int Iceman_totalNum=1; Iceman* red_iceman[100]; red_iceman[Iceman_totalNum] = new Iceman(); cout << t << " red iceman " << " born with strength " << red_iceman[Iceman_totalNum]->hp << "," << Iceman_totalNum << " iceman in red headquarter" << endl;有什么问题

这段代码定义了一个Iceman类,并且创建了一个名为red_iceman的指针数组,数组大小为100。同时,代码通过new运算符为red_iceman数组中的第Iceman_totalNum个元素分配了内存空间,创建了一个新的Iceman对象。
问题可能出现在下面这行代码中:
```
cout << t << " red iceman " << " born with strength " << red_iceman[Iceman_totalNum]->hp << "," << Iceman_totalNum << " iceman in red headquarter" << endl;
```
在这行代码中,程序访问了red_iceman数组中的第Iceman_totalNum个元素的hp属性。但是,在这个时候,Iceman_totalNum的值为1,而red_iceman数组中只有一个元素,因此访问red_iceman[1]会导致数组越界错误。应该将Iceman_totalNum的初始值设置为0,或者在创建新的Iceman对象之前将Iceman_totalNum的值加1。

这段代码中有一个问题:在创建 `red_iceman` 数组时,数组的下标应该从0开始,而不是从1开始,因为C++中的数组下标是从0开始的。因此,将 `Iceman_totalNum` 初始化为0,并在创建 `red_iceman` 对象时使用 `red_iceman[Iceman_totalNum++] = new Iceman();` 来避免这个问题。
定义了一个Iceman类,有数据成员hp,Iceman_totalNum=0; Iceman* red_iceman[100]; red_iceman[Iceman_totalNum] = new Iceman(); cout << " red iceman " << " born with strength " << red_iceman[Iceman_totalNum]->hp << "," << Iceman_totalNum << " iceman in red headquarter" << endl;有什么问题
这段代码中存在指针内存泄漏的问题。虽然在创建Iceman对象后将其地址存储在red_iceman数组中,但当程序结束时没有释放这些对象所占用的内存空间。应该在程序结束前使用delete运算符来释放这些对象所占用的内存空间,避免内存泄漏。另外,变量Iceman_totalNum的值应该在每次创建Iceman对象时进行更新,否则会导致数组越界的问题。
