Help with Depth First Search

Code:

class arc
{
  public:
    int adj;
    int weight;
    arc(){}
    arc(int a)
    {
        adj = a;
    }
};

int bfs(int v,int n) //using queues
    {
        int i, front, rear;
        int que[20];
        front = rear =  - 1;

        cout << v;
        visited[v] = true;
        rear++;
        front++;
        que[rear] = v;

        while (front <= rear)
        {
            v = que[front];
            front++;
            for (i = 1; i <= n; i++)
            {
                if ((arcs[v][i] == 1) && (visited[i] == false)) //error line
                {
                    cout << i;
                    visited[i] = true;
                    rear++;
                    que[rear] = i;

can someone help me with my problem? please i really2x need all your help thanks advance

Since you seem to be using quite a few global variables, you will need to post the smallest possible complete program that illustrates your problem. For example how is arcs defined? How is visited defined?
