struct node {
    char course[25];
    char category[20];
    char prereq[50];
    char notes[50];

{
    FILE *fp;
    char *filename = argv[1];

    int num = 5, i = 0, j =0, count = 0;
    struct node *d = malloc(num * sizeof(struct node));
    char** complete = malloc(num * sizeof(char*));
    printf("%s\n", filename);


    if( (fp = fopen(filename, "r")) == NULL )
