Thread: inserting into linked list

Alright, so I know that I'm supposed to use strcpy for strings, but I just can't get it to work. The program will just crash after entering the first bit of information. Here is the code I have for the insert function:

Code:

void insert(struct vehicle** head, char* make, char* model, int year, char* color, char* license)
{
    struct vehicle* newvehicle;
    struct vehicle* crnt = (*head);
    
    newvehicle = malloc(sizeof(struct vehicle));
    newvehicle->make = make;
    newvehicle->model = model;
    newvehicle->year = year;
    newvehicle->color = color;
    newvehicle->license = license;
    
    
    
    
    if ((*head) == NULL || (*head)->license > license)
    {
        strcpy((*head),newvehicle->next);
        strcpy(newvehicle,(*head));
        return;
    }
    
    while(crnt->next != NULL && crnt->next->license < license)
    {
        strcpy(crnt->next, crnt);
    }
    
    strcpy(crnt->next,newvehicle->next);
    strcpy(newvehicle,crnt->next);
}

My intro teacher never went over strcpy or strcmp at all, so I really don't know how to use them.

So, are you and vidioholic and SkidMarkz the same person or what? (If not, you should check their recent posts.)

You would need to strcpy the license over. I don't know what you're trying to do with all the other strcpy's.

Remember to allocate memory for all of your strings before using strcpy
