Question

一道C++题目的错误，关于char*的，请帮忙解决啊

#include <iostream.h>

void main()
{
class people
{
public:
people()
{
firstname=secondname=race=NULL;
age=0;
}
~people()
{
delete []firstname;
delete []secondname;
delete []race;
}
void setFirstname(char *_firstname)
{
name =new char[strlen(_firstname)+1];
strcpy(name,_name);
}
char *getFirstname()
{
return firstname;
}
void setSecondname(char *_secondname)
{
name =new char[strlen(_secondname)+1];
strcpy(name,_secondname);
}
char *getSecondname()
{

return secondname;
}
void setRace( char *_race)
{
race = new char[strlen(_race)+1];
strcpy(race,_race);
}
char *getRace()
{
return race;
}
void setAge(int _age)
{
age = _age;
}
int getAge()
{
return age;
}
void output()
{
cout<<"姓名"<<firstname<<secondname<<ends
<<"年龄"<<age<<ends
<<"种族"<<race<<endl;
}
private:
char *firstname;
char *secondname;
int age;
char *race;
};
people father;
people mother;
people girl;
father.setFirstname("陈");
father.setSecondname("冠希");
father.setRace("汉族");
father.setAge(28);
mother.setFirstname("阿");
mother.setSecondname("娇");
mother.setRace("汉族");
mother.setAge(23);
girl.setFirstname(father.getFirstname);
girl.setSecondname(mother.getSecondname);
girl.setAge(16);
girl.setRace(mother.getRace);
cout<<"爸爸:"<<endl;
father.output();
cout<<"妈妈"<<endl;
mother.output();
cout<<"女儿"<<endl;
girl.output();
}
girl.setFirstname(father.getFirstname);
girl.setSecondname(mother.getSecondname);
girl.setRace(mother.getRace);
其中这三句都发生同样的错误cannot convert parameter 1 from 'char *(void)' to 'char *'
我不明白为什么类里返回的类型变成了char *(void)了。
请详细解释啊，谢谢啊

#include <iostream.h>

{
firstname=secondname=race=NULL;
age=0;
}
~people()
{
delete []firstname;
delete []secondname;
delete []race;
}
void setFirstname(char *_firstname)
{//将name改为firstname,_name改为_firstname，并包含头文件<string.h>
name =new char[strlen(_firstname)+1];
strcpy(name,_name);
}
char *getFirstname()
{
return firstname;
}
void setSecondname(char *_secondname)
{ //将name改为secondname
name =new char[strlen(_secondname)+1];
strcpy(name,_secondname);
}

mother.setAge(23);
girl.setFirstname(father.getFirstname); //改为girl.setFirstname(father.getFirstname());
girl.setSecondname(mother.getSecondname); //改为girl.setSecondname(mother.getSecondname());
girl.setAge(16);
girl.setRace(mother.getRace); //改为girl.setRace(mother.getRace());
cout<<"爸爸:"<<endl;
father.output();
cout<<"妈妈"<<endl;
mother.output();
cout<<"女儿"<<endl;
girl.output();
}
//按照提示改完后能够运行，不过LZ将类放在函数里面，这种习惯可不好哦。要学会用C++对象的方法编程.

//我要分啊，嘿嘿。

Answer 2

没有编译器,不能帮你排错
你定位到错误附近
将 char*(void)错误的位置
强制转换为 (char*)

Answer 3

在那三句的get函数后面加个括号吧，是函数来的，不是属性。
另外，我是长了见识了，第一次看到有人再main里面定义类的。

Answer 4

girl.setFirstname(father.getFirstname);
因为father.getFirstname()是个函数,加个()就行了;也许还会有连锁的错误,自己找吧...

Answer 5

调用函数没加括号
getFirstname()
getsecondname()...
