here is code

#include <iostream.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include <string.h>





struct doc_words
       {
        char words[30];

        else
        return(p);

struct doc_words *AddWords( char text[30])

        newNode=getmem();
       newNode->words[20]= text[30];

            {

Some of the corrected errors are

void AddWords( char text[30]) // you are not returning anything, so use void.
{
    newNode=getmem();
    strncpy(newNode->words,text, 29); // you can't just assign character arrays. Use strncpy to copy the contents.
    newNode->next=head;
    head=newNode;
};

Also once you are finished with the program, free the memory used in the list, or you will be leaking memory.

thank you so much, it is now saving in the list.
