    Finally got this C program to run but can't figure out the standard deviation problem

    Hey guys, I lurk these forums a good amount but never registered to post myself. I have this C++ assignment I'm working on that is now overdue and killing me! If anyone has any suggestions i'd greatly appreciate it!



    Okay here's a link to the actual project. It's already overdue because I can't figure it out and get it to run no matter what I try!
    http://www.cs.ucf.edu/courses/cop322...s/Program4.pdf

    This is the code I have, completed:


    #include <stdio.h>
    #include <math.h>


    int main() {

    int num_shows, num_contestants, num_judges, sd_threshold;
    double average;

    // Open the text file.
    FILE* ifp = fopen("ucfidol2.txt", "r");

    //scanning info from text file
    fscanf(ifp, "%d", &num_shows);
    fscanf(ifp, "%d%d%d", &num_contestants, &num_judges, &sd_threshold);

    //declaring array size by text file
    int score[num_contestants][num_judges];
    int i, j;

    //populates 2d array with numbers from text file
    for (i = 0; i < num_contestants + 1; i++)
    for (j = 0; j < num_judges; j++)
    fscanf(ifp, "%d", &score[i][j]);

    int judges_score[num_judges];
    int index;

    for (i = 0; i < num_judges; i++)
    scanf("%d", &average[i]);

    int val = 0;
    double sum = 0;

    //adds judges scores together
    for (val=0; val <= num_contestants-1; val++) {
    sum = sum + score[val][0];
    //testing
    printf("val = %d\n", val);
    printf("score[0][%d] = %d\n", val, score[val][0]);
    printf("sum = %lf\n", sum);
    }

    //calculates average of judges scores
    average = sum / num_contestants;
    printf("average = %lf\n", average);


    //NEED THIS CODE!!!



    //printing
    //printf ("%d\n", score[0][0]);
    //printf ("%d\n", score[0][1]);
    //printf ("%d\n", score[0][2]);
    //printf ("%d\n", score[0][3]);
    //printf ("%d\n", score[1][0]);
    //printf ("%d\n", score[1][1]);
    //printf ("%d\n", score[1][2]);
    //printf ("%d\n", score[1][3]);
    //printf("num_shows = %d\n", num_shows);
    //printf("num_contestants = %d\n", num_contestants);
    //printf("num_judges = %d\n", num_judges);
    //printf("sd_threshold = %d\n", sd_threshold);

    // Close the file.
    fclose(ifp);

    system("PAUSE");
    return 0;
    }



    I can't figure out the rest of the code for the life of me, I've tried a few things

    someone sent me this (has different variables but it's easier to see how it works) but I can't make it work and get anything to print out...

    for (i=0; i<judges; i++) {
    sum=0
    for (j=0; j<contestants; j++) {

    sum = ((pow(judavg[i]-score[j][i],2) + sum;
    }

    sd = sqrt(sum/cont);
    if (sd > std)
    cheaters[i]=1
    else
    cheaters[i]=0


    Can anyone fill in the blanks for me? Also if I have any other errors please let me know!

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
