UC知道C++简单程序出问题！
来源：百度知道 编辑：UC知道 时间：2024/07/01 00:39:45
#include<iostream>
using namespace std;
class Person
{
int age;
string sex;
double height;
double weight;
string name;
};
class Classmate: public Person
{
char classname[9];
char school[9];
void setclassname(char *p){classname=p;}
};
class Colleague: public Person
{
char organization[9];
char department[9];
};
class Leader: public Colleague
{
}
main()
{
char u[9]="happy";
Colleague a;
a.setclassname(u);
}
请问问题出在哪了啊！怎么修改啊
using namespace std;
class Person
{
int age;
string sex;
double height;
double weight;
string name;
};
class Classmate: public Person
{
char classname[9];
char school[9];
void setclassname(char *p){classname=p;}
};
class Colleague: public Person
{
char organization[9];
char department[9];
};
class Leader: public Colleague
{
}
main()
{
char u[9]="happy";
Colleague a;
a.setclassname(u);
}

return 0;

修改完毕。问题如楼上所示。自己研究研究下。加油
classname在类中是一个字符数组，不是一个指针，它是不能被重新赋值的！
可以把它定义成指针，或者拷贝字符串给它。
Colleague类中也没有setclassname这个函数，基类person里面也没有，根本不可以调用！
修改如下
class Classmate: public Person
{
char *classname;
char school[9];
void setclassname(char *p){c
