strcpy函数怎么用呀?

[hailun]

#include<iostream.h>
#include<string.h>
class ca
{
char *ps;
public:
ca(){ps=0;}
ca(char *s){
ps=new char[strlen(s)+1];
strcpy(ps,s);//STRCPY的作用不是把后面指向的字符串拷贝到前面的字符串中吗?这个S ,PS不是地址吗?
}
ca(ca &s);
~ca(){if(ps) delete[]ps;}
char *gets(){return ps;}
};
ca::ca(ca &s)
{
if(s.ps){ps=new char[strlen(s.ps)+1];
strcpy(ps,s.ps);}
else ps=0;
}
void main()
{
ca s1("china!");
ca s2(s1);
cout<<"s1="<<s1.gets()<<'\t';
cout<<"s2="<<s2.gets()<<'\n';
}
