#include<iostream.h>
#include<stdio.h>
class A
{
int x,y;
public:
int z;
A(int xx=0;int yy=0;int zz=0):x(xx),y(yy),z(zz){}
friend void in(A);
friend void sh(A);
};
void in(A a1)
{
cout<<"input x,y:";
cin>>a1.x>>a1.y>>a1.z;
cout<<a1.x<<" "<<a1.y<<" "<<a1.z<<endl;
}
void sh(A)
{
cout<<a1.x<<" "<<a1.y<<" "<<a1.z<<endl;
}
void main()
{
A a1(11,22,33);
sh(a1);
in(a1);
sh(a1);
}
调试的时候经常会有error C2143: syntax error : missing ';' before '}' 这个错误怎么解决

A(int xx=0;int yy=0;int zz=0):x(xx),y(yy),z(zz){}

应该中间的分号改为逗号；

void sh(A)
改为void sh(A a1)

你可能的问题是编译器的问题.
若用vc6的ide,可能要在头上加
#include "stdafx.h"
