错在那里了!!
#include <iostream.h>
class dataclass
{
private:
int pdm1;
public:
dataclass(int value);
int pdm2;
int pm(void);
};
dataclass::dataclass(int value)
{
pdm1=value;
}
int dataclass::pm(void)
{
return pdm1;
}
void main()
{
dataclass dataobj(1);
dataobj.pdm2=2;
cout<<"dataobj.pdm2=%d"<<
dataobj.pdm2<<"\n";

cout<<"dataobj.pdm1=%d"<<
dataobj.pdm1<<"\n";
}

private:
int pdm1;

改成：

public:
int pdm1;

[leyt]

cout<<"dataobj.pdm1=%d"<<
dataobj.pdm1<<"\n";

改为cout<<"dataobj.pdm1=%d"<<dataobj.pm（）<<"\n";

错误在这：dataobj.pdm1

唉。。。。。。。。。。。。。。。。。

int pdm1为private,但你又在main()中访问了它

[xiaoyunet]

cout<<"dataobj.pdm2=%d"<<
dataobj.pdm2<<"\n";
是什么意思，你以为cout是printf呐。
难怪Andy84920(你也不懂)叹气呢。

你的程序应该是一个小的例子，不知道你通过这样的例子想知道什么，也就是说当初你写这段程序的目的是什么？看不出来啊。
