一个小问题. 关于类成员变量初始化

[nickr]

代码如下:
class CFoo
{
CFoo(void){}

CFoo(int a){}
};


class CBar
{
CFoo foo;
CFoo foo2(1); // error C2059: syntax error : 'constant'
};

我想用 CFoo 类的第二种构造函数来构造 foo2 对象. 用什么法子?
(不想用指针来实现)

你怎么能在类里构造对象呢？
应该写在函数中才行的。

[luopeng]

class CBar
{
public:
CBar():foo2(1)
{
}
private:
CFoo foo2;
};

搞定. 谢谢.
如下:
C:\Documents and Settings\Administrator\桌面>type temp.cpp
#include "iostream.h"

class CFoo
{
public:
CFoo(void){ cout<<"Form 1 \n";}

CFoo(int a){ cout<<"Form2";}
};


class CBar
{
public:
CBar():foo2(1)
{
}

protected:
CFoo foo;
CFoo foo2;
};


void main(void)
{
CBar bar;

}
