c++ - (c++) 在类中声明类成员

Question

我正在尝试在每个 CClient 类中创建一个 CBuffer 成员，如下所示：

#ifndef CCLI_INC
#define CCLI_INC
#include "CBuffer.h"
#include "main.h"

    class CClient
    {
    private:

        CBuffer *m_buffer;


    public:
        CClient();



    };

但是这段代码给了我

 error C2143: syntax error : missing ';' before '*'
 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

虽然我已经包含了 cbuffer.h 头文件，但它给出了这个奇怪的错误..

转发声明CBuffer并丢失include.

#ifndef CCLI_INC
#define CCLI_INC
#include "main.h"
class CBuffer;
class CClient
{
private:

    CBuffer *m_buffer;
public:
    CClient();
};
