Bubble Sort from any file in C

I have never heard of "Bubble sort" before so I went look up on Wikipedia under Pseudocode implementation.

procedure bubbleSort( A : list of sortable items )
    n = length(A)
    repeat
        swapped = false
        for i = 1 to n-1 inclusive do
            /* if this pair is out of order */
            if A[i-1] > A[i] then
                /* swap them and remember something changed */
                swap( A[i-1], A[i] )
                swapped = true
            end if
        end for
    until not swapped
end procedure

This is for part of CS105 I am new a student. I have been stuck on this is third of my assignments that are due later today. I have finished the codes from my understanding try to use this pseudo-code convert to C program. I have completed the code so already. Can anyone help to fix this for me or what am I doing wrong? I am really hard to understand this "Bubble Sort" in C code.

/* 5 points */
#include <stdio.h>
#include <string.h>

#define MAXLEN 1000

/**
 * Fill in the bubblesort function: https://en.wikipedia.org/wiki/Bubble_sort
 * Using this pseudo-code in Wikipedia, convert to C code.
 */
void bubblesort (char *A[], int n) {
  int i, j, temp;

  for (i = 0; i < length; i++) {
    for (j = 0; j < length - 1; j++) {
      if (*A[j + 1] < *A[j]) {
        temp = *A[j];
        *A[j] = *A[j + 1];
        *A[j + 1] = temp;
      }
    }
  }
}

/**
 * Create a main function that opens a file composed of words, one per line
 * and sorts them using the bubble-sort algorithm.
 * Usage: "Usage: %s <file>\n"
 * Example input/output:
 * ./p8 testfile
 * Bob
 * Bubbles
 * Butters
 * Dave
 * ...
 */
int main (argc char, *argv[]) {
  int intRC;
  if (argc < 2) {
    printf ("Usage: %s <file>\n");
    intRC = -1;
  } else {
/*This needs attention:
 * argv[2] will contain a single string
 * array[] is a character array not a float, atof tries to convert the string to a float
 * the parameter passed to bubble_sort needs to be an array of pointers, not a single pointer
 * What you need to do...
 *   Try to read the file specified by argv[2] into a buffer (char*)
 *   Split the buffer into an array of strings
 *   Pass that array to your bubble sort routine
 *   Implement lots of error checking:
 *    Does the file exist?
 *    Can it be read?
 *    Is there anything to process? (does the file contain anything to sort)
 */
    char array[] = atof(argv[2]);
    bubble_sort (array, 100);
    intRC = 0;
    while( intRC<intItems ) {
      printf("%c\n", array[intRC]);
      intRC++;
    }
  }
  // prints print new lines from file
  return intRC;
}

This is what I used from file to test, but can be any else too that's why I used atof(argv[2]); to get any file.
