帮我看下这段程序
#include <iostream.h>
class Point
{
public:
Point(int xx=0,int yy=0)
{
X=xx;
Y=yy;
countP++;
}
Point(Point &p);
int GetX()
{
return X;
}
int GetY()
{
return Y;
}
void Get()
{cout < < "object id= " < <countP < <endl;
}
private:
int X,Y;
static int countP;
}
Point::Point(Point &p)
{
X=p.X;
Y=p.Y;
countP++;
}
int Point::countP=0;
void main()
{
Point A(4,5);
cout < < "Point A( " < <A.GetX() < < ", " < <A.GetY() < < ") ";
A.Get();
Point B=A;
cout < < "Point B( " < <B.GetX() < < ", " < <A.GetY() < < ") ";
B.Get();
}
在VC6.0环境下调试，出现问题：
一、error C2533: 'Point::Point ' : constructors not allowed a return type
二、error C2264: 'Point::Point ' : error in function definition or declaration; function not called
执行 cl.exe 时出错.
请问怎么修改啊？
[解决办法]
// ...
int X,Y;
static int countP;
}; // 这里少了一个分号
[解决办法]
.........
private:
int X,Y;
static int countP;
}
-------------------------------
你定义类时，漏写了分号啊！！
即是
......................
private:
int X,Y;
static int countP;
}; -> 此处加上分号啊！！
[解决办法]
#include <iostream.h>
class Point
{
public:
Point(int xx=0,int yy=0)
{
X=xx;
Y=yy;
countP++;
}
Point(Point &p);
int GetX()
{
return X;
}
int GetY()
{
return Y;
}
void Get()
{cout < < "object id= " < <countP < <endl;
}
private:
int X,Y;
static int countP;
};
Point::Point(Point &p)
{
X=p.X;
Y=p.Y;
countP++;
}
int Point::countP=0;
void main()
{
Point A(4,5);
cout < < "Point A( " < <A.GetX() < < ", " < <A.GetY() < < ") ";
A.Get();
Point B=A;
cout < < "Point B( " < <B.GetX() < < ", " < <A.GetY() < < ") ";
B.Get();
}
[解决办法]
private:
int X,Y;
static int countP;
};
是呀!这个}后应该加上一个分号,加上后就正确了!
[解决办法]
类声明后面忘记分号了
