Thread: struct,line of of characters

I was like trying to create a program,to edit and modify text .
So I created 2 linked lists, one for the characters and one for the lines.

the program i created was :

Code:

 #include <stdio.h>

typedef struct node{
    char cHar;
    struct node *next;
}character;

typedef struct sentence{
    character word;
    struct sentence *next;
}line;


int main(void){
    
    character *d;
    line *e;
    
    e->word.cHar='d';
    
    e->word=e->word.next;
    e->word.cHar='a';
    
    e->word=e->word.next;
    e->word.cHar='v';
    
    e->word=e->word.next;
    e->word.cHar='i';
    
    e->word=e->word.next;
    e->word.cHar='d';
    
    
}

but it doesn't work.Can some one help as to how to go on add the 2nd character and how to manually assign it some some letter.

And also how to allocate some memory space for the new letter.
All replies posted to this thread is much appreciated.
Thanks Alot
