求解，怎么反转一个单词，需要包括以下的方法。需按要求

Question

需要创建一个程序，用户可以输入一个单词，反转该单词，并使用链接列表检查该单词是否为回文单词。在程序结束时，它将列出输入单词中的所有回文单词。
程序必须包括以下方法/功能：
a) menu() – as interface for the user
b) add_word(string) – to enter the word to the list
c) show_list() – to display the lists
d) reverse_word(string) – to reversed the word
e) palindrome(string) – to check if the word is palindrome
f) palindrome_list() – to list all of the palindrome words
g) delete_list() – to delete list
Example, segment of output:
How many words you want to enter: 3
Please enter a word: kayak
Please enter a word: madam
Please enter a word: world

Reversed the word: kayak
Reversed the word: madam
Reversed the word: dlrow

kayak, is a palindrome word.
madam, is a palindrome word
world, is not a palindrome word.

List of the palindrome words: kayak, madam
Declaration node and functions:
//declaration of node
struct Node{
string p_word;
Node *plink;
};

void menu();
void add_word(string);
void show_list();
void reversed_word(string);
void palindrome(string);
void palindrome_list();
void delete_list()

#include <iostream>
#include <cstring>
using namespace std;
 
int main(){
    const int n=501;
    char a[n];
    int len,s=0,c=0,k=0;
    cin.getline(a,n);
    len=strlen(a);
    for(int i=0;i<len;i++){
        if(a[i]==' '||i==len-1){
            c++;
            if(i==len-1) k=i;
            else k=i-1;
            for(int j=k;j>=s;j--) cout<<a[j];
            if(c==1){
                cout<<" ";
                c=0;
            } 
            s=i+1;
        }
    }
    cout<<endl;
    return 0;
}
