Aghhh vectors

  1. Oct 8, 2006 #1
    Ok, I'm trying this code in Dev-C++

    int main(int argc, char **argv)
    {
    double **a;
    double *b;
    // double *m;
    int n, iter;
    double tol;

    b = new double[n];

    a = new double*[n];
    for (int i = 0; i < n + 1; i++)
    a = new double[n];

    // m = new double[n];

    cout << "I'm ready to continue =)!!!";

    system("PAUSE");
    return 0;
    }

    If I omit the m vector, the program will run and not disappear in a second and it will be ready to continue.. but when I declare the m vector without even doing anything with it... it just runs and quits quicker than I can blink my eye...! Why is this happening =(?

    Forget this post, I just realized I had to initialize n before doing any of this ... tehe =)

    n is undefined.

    Edit: Sorry, just saw your follow up.
