adding nodex

[Colin]

Hi,
Can anyone help me with this problem.
I am going to store a graph in a linked adjacency list, (cities and distance between them) and I am taking in the city input first. I am having trouble moving on to the next vertexnode(incrementing) to add the cities to the linked list. I can see this because I only get the last one I entered to display.

My structure looks like this:


struct arcnode{
char vertex[10];
int weight;
struct arcnode *nextarc;
};

struct vertexnode{
char city[10];
struct vertexnode *nextvertex;
struct arcnode *nextarc;
};

Anyone any ideas, much appreciated.
Thanks
Colin

Don't you have any functions that act on these structures? Without them, nobody will be able to help you (unless they write them for you, which is BAD BAD BAD )

Shame on you Biosx, tut tut, he who has little faith!!!
Thanks but I figured out my error after I posted my problem.
Thanks anyway,
Colin


/*This function inserts a vertex node into an Linked */
/* Adjacency List */
void insert_vertex(struct vertexnode **list)
{

while ( (*list)->nextvertex) /* Get to end of vertex list */
*list = (*list)->nextvertex;

(*list)->nextvertex = new(struct vertexnode);
*list = (*list)->nextvertex;

clrscr();
printf ("\t\t New City (Vertex)\n");
printf ("\t\t-------------------\n\n");
printf ("Please enter a name for the city: "); /* Input City name */
scanf ("%s", (*list)->city);
printf ("\n\nConfirmation of city name: %s\n", (*list)->city);
getche();
}

Oh I had faith in you. I just wanted you to post your functions :-D

Glad to hear you figured it out. You know, I notice that if I ever get stuck, I usually find the problem by just getting ready to post the code

BTW: Next time, use the [ code ] tags
