Question

晚上好，我是C ++的新手，我一直遇到麻烦。

现在，我正在尝试创建一个List，在经过大量的撤消和更正之后，我发现了这个我无法解决的错误。

#define MAXLIST 100
template <typename T>

class List {
 private:
int maxList;
int last = 0;
T* List;
 public:
List();
explicit List(int tam);
bool listIsFull();
void destroyList();

List<T>() {
last = -1;
maxList = MAXLIST;
list = new T[maxList];
}

List<T>(int tam) {
last = -1;
maxList = tam;
list = new T[maxList];
}


void destroyList() {
last = -1;
}

bool listIsFull() {
if(last == MAXLIST -1)
    return true;
else
    return false;
    }
}

两个方法destroyList（）和listIsFull（），在我的IDE中显示如下错误：'无法重载' 两个构造函数都显示如下错误：'不命名类型'

那是什么，我做错了？提前谢谢。

你的代码出现在我面前的样子，你试图为你的类做原型，然后在它下面提供实现，我只是添加了正确的范围和模板操作符。

用C ++列出重载方法？
