Deleting a node from linked list in C

Question

My problem is deleting a node from linked list.

I have two structs :

typedef struct inner_list 
{
 int count;
 char word[100];
 inner_list*next;
}          


        

Answer 1

try this (only for the outer list, it wont release the inner one):

void delnode(outer_list *head,char num[100]) 
{ 
    outer_list *temp, *m. *helper; 
    temp=head; 
    while(temp!=NULL) 
    { 
        if(strcmp(temp->word,num)==0) 
        { 
            if(temp==head) 
            { 
                head=temp->next; 
                free(temp); 
                return; 
            } 
            else 
            { 
                m = temp;
                temp = temp->next;
                helper->next = temp; //link the previous item
                free(m); 
                return; 
            } 
        }
        else 
        { 
            helper = temp;
            temp= temp->next; 
        } 

    } 
    printf(" ELEMENT %s NOT FOUND ", num); 
}
