SOS下午就考试，谁能帮我改错

[scuthdd]

class Sample {
public:
Sample(int a=0, float b=0);
Sample(Sample & p) { sa = p.sa;
sf=Sample::sf;
p=p.p; }
~Sample();
void show();
private:
int sa;
static float sf;
char *p;
};



error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'int *' (or there is no acceptable conversion)
Error executing cl.exe.

class Sample {
public:
Sample()
{
int a = 0;
float b = 0;
pt = NULL;
}

Sample(Sample & p)
{
sa = p.sa;
sf = Sample::sf;
pt = p.pt;
}

~Sample();
void show();

private:
int sa;
static float sf;
char *pt; // 請注意,成員變量不可以和類同名
};

楼上的说法有误，正确的改法如下：
class Sample {
public:
Sample(int a=0, float b=0);
Sample(Sample & p) { sa = p.sa;
sf=Sample::sf;
// p=p.p; // 此句有错 改为：
this->p = p.p;
}
~Sample();
void show();
private:
int sa;
static float sf;
char *p;
};

两者都行阿
谢谢大家咯，我要去考试咯

3q very much

检查sa = p.sa
可能你需要重载"="操作符才能赋值
也可能类型转换错误

[maskzha]

类型转换错误
class Sample {
public:
Sample(int a=0, float b=0);
Sample(Sample & p) { sa = p.sa;
sf=Sample::sf;
p= p.p;
}
~Sample();
void show();
private:
int sa;
static float sf;
char p;
};

你的答案已经改变了题意！！
申明一个char *p有错吗？？？
我的目的是要求保留char *p，那么构造函数怎么改？？？
