pure specifier can only be specified for functions

源码:版本vc6.0

class CTest{
private:
	int index = 0;
	char* name = NULL;
public:
	void setname(char* str);
};
void CTest::setname(char* str){
	name = str;
	printf("%s",name);
}
int main(int argc, char* argv[])
{
	CTest tt;
	char* name = "Hello,kitty!\n";
	tt.setname(name);
	return 0;
}


编译后提示:

这里出问题的原因是:成员变量index和name在声明时被初始化了,将index=0和name=NULL的初始化去掉。即:

class CTest{
private:
	int index;
	char* name;
public:
	void setname(char* str);
};


 

经Baidu还有一个可能的原因是静态成员变量的原因,具体见http://blog.csdn.net/zxxyyxf/article/details/6432612
