我正在学习一本关于数据结构的书,并在链表示例中编写了他们的节点,我收到了这个错误:
and Everything.cpp|7|error: expected unqualified-id before "int"|
and Everything.cpp|7|error: expected `)' before "int"|
||=== Build finished: 2 errors, 0 warnings ===|
节点的代码是:
typedef struct Node
{
struct Node(int data) //Compile suggest problem is here
{
this-> data = data;
previous = NULL;
next = NULL;
}
int data;
struct Node* previous;
struct Node* next;
} NODE;
我不熟悉结构,我正在使用Code :: blocks进行编译。有谁知道什么是错的?
答案 0 :(得分:5)
代码示例错误。构造函数声明前面不应该有关键字struct
。它应该是:
typedef struct Node
{
Node(int data) // No 'struct' here
{
this-> data = data;
previous = NULL;
next = NULL;
}
int data;
struct Node* previous;
struct Node* next;
} NODE;
