what does this expression do for(d=0;d<n-c-1;d++) : 
I was trying to figure out how this inner loop work In This below code but I couldn't understand, the part that I really struggle to understand is (d<n-c-1)// inner for loop// 


include <stdio.h>
 
int main() {
 
  int array[100], n, c, d, swap;
 
  printf("Enter number of elements\n");
  scanf("%d", &n);
 
  printf("Enter %d integers\n", n);
 
  for (c = 0; c < n; c++)
    scanf("%d", &array[c]);
 
  for (c = 0; c < (n - 1); c++) {
 
    for (d = 0; d < n - c - 1; d++) {
 
      if (array[d] > array[d + 1]) /* For decreasing order use < */
      {
        swap = array[d];
        array[d] = array[d + 1];
        array[d + 1] = swap;
      }
    }
  }
 
  printf("Sorted list in ascending order:\n");
 
  for (c = 0; c < n; c++)
    printf("%d\n", array[c]);
 
  return 0;
