    I do not quite get your point. you say I have a \n in the line. I think so too. It's at the end of the line. Am I supposed to have it in the line? I think I need \n for fgets to find out the line. And what do you mean by treat it as a part of the word? And the code is fine working with \n but I can not use it for " ".

    I found out the problem above, I don't know why but the code works fine on another compiler.

    A new question how to insert string into a list.
    I tried numbers. It's fine. but not with string.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    struct node {
      char string;
      struct node *next;
    };
    
    int main()
    {   
        struct node *root;       
        struct node *conductor;  
    
        root = malloc( sizeof(struct node) );  
        root->next = 0;   
        root->string = "test string 1";
        conductor = root; 
        if ( conductor != 0 ) {
            while ( conductor->next != 0)
            {
                conductor = conductor->next;
            }
        }
    
        conductor->next = malloc( sizeof(struct node) );  
    
        conductor = conductor->next; 
    
        conductor->next = 0;         
        conductor->string = "test string 2";
        conductor = root;
        if ( conductor != 0 ) { 
            while ( conductor->next != 0 ) {
                printf( "%d\n", conductor->string );
                conductor = conductor->next;
            }
            printf( "%d\n", conductor->string );
        }
        return 0;
        
    }
    I try to do some test. but it prints out integers not string.

    this code shouldn't work
    string is char - it cannot store the string

    it should be char* and dinamically allocated or char string[BUF_SIZE]

    and you should use string manipulation functions like strcpy
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    inside struct I need to have :

    Code:
    struct node {
      char *string;
      struct node *next;
    };
    can you give me some more details about strcpy(structure I can find out)?
    I mean where shall I use it?

    here?
    Code:
    conductor->string = "test string 2";
    How do I copy string to the node?

    make sure that you have enough room for the string to copy to.

    That is just about strcpy itself. How can I use this to insert string to the struct?
