C :

#include<stdio.h>
int i = 1;//定义全局变量，每次调用后加1
void Hanoi(int n, char A, char B, char C)
{
     
    if (n == 1)//如果只有一个直接从A移到B   "%2d-(%2d):%c==>%c\n"
    {
    printf("%c To %c\n",A,C);
     
    }
    else
    {
   Hanoi(n - 1, A, C, B);//把n - 1个从A移到C借助B
     
    printf("%c To %c\n",A, C);
    Hanoi(n - 1, B, A, C);//把n - 1个从C移到B借助B
        
    }
     
}
int main()
{
    int n;
    char A = 'A'; //定义ABC表示三个柱子
    char B = 'B';
    char C = 'C';
    scanf("%d", &n);
    Hanoi(n, A, B, C);
     
    return 0;
}

C++ :

#include <iostream>
using namespace std;

//n代表盘子的数量，a代表放盘子的塔，b代表中间的辅助塔，c代表目标塔 
void hanNuo(int n,char a,char b,char c){
	if(n > 0){
		//把上面的n-1个盘子，从a塔借助于c塔放到b塔上 
		hanNuo(n - 1,a,c,b);
		//把最下面的第n个盘子，从a移动到c 
		cout<<a<<" To "<<c<<endl;
		//将b塔上的n-1个盘子，从b移动到c借助于a
		hanNuo(n - 1,b,a,c); 	 	
	}
}

int main(){
	int n;
	cin>>n;
 	hanNuo(n,'A','B','C');
}

Python :

def hanoi(n,A,B,C):
    if n==1:
        print(A,"To",C)
    else:
        hanoi(n-1,A,C,B)
        print(A,"To",C)
        hanoi(n-1,B,A,C)
x=int(input())
hanoi(x,"A","B","C")
