谭浩强的实验题目。。。就问这个程序运行结构是否正确？除了没有赋值以外 哪里有错误？

Question

#include <iostream>using namespace std;class CPoint{public: void Set(int x,int y); void Print();private: int x; int y;};void CPoint::Set(int x,int y){ x = x; y = y;}void CPoint::Print(){ cout<<"x="<<x<<",y="<<y<<endl;}void main(){ CPoint pt; pt.Set(10,20); pt.Print();}
