#include <iostream.h>
#include <stdio.h>
void hanoi(int n,char x,char y,char z);
void move(char x,int n,char y);
void main()
{
int num;
char A,B,C;
cout<<"Please enter the number of disks num:";
cin>>num;
hanoi(num,A,B,C);
}
void hanoi(int n,char x,char y,char z)
{
if(n==1)
move(x,1,z);
else{
hanoi(n-1,x,z,y);
move(x,n,z);
hanoi(n-1,y,x,z);
}
}
void move(char x,int n,char y)
{

cout <<"move\t"<<n<<"from\t"<<x<< "to"<< y<<endl;
}
程序没有错误
但运行的时候却有乱码
最后一行是不是写法不正确 ？

把Hanoi 函数的参数该成Hanoi(n,'A','B','C')就OK 了

可以不用move函数,在原程序稍做改动,如下:
#include <iostream.h>
#include <stdio.h>
void hanoi(int n,char x,char y,char z);
void main()
{
int n;

cout<<"Please enter the number of disks num:"<<endl;
cin>>n;
hanoi(n,'A','B','C');
}
void hanoi(int n,char x,char y,char z)
{
if(n==1)
cout<<x<<"\tmoveto\t"<<z<<endl;
else{
hanoi(n-1,x,z,y);
cout<<x<<"\tmoveto\t"<<z<<endl;
hanoi(n-1,y,x,z);
}
}
