the table has 4 rows and 5 columns
i done some code but am stuck

  1. void print_sales(float sales[][MAX_SIZE])
  2. {
  3.  
  4. float *temp[ARRAY_SIZE][MAX_SIZE];
  5. temp[0][0]=&sales[0][0];
  6.  
  7. for (int i=0;i<MAX_SIZE-1;i++)
  8.      for (int j=0;j<MAX_SIZE;i++)
  9.           {
  10.           temp[i][j]=&sales[i][j];
  11.           }

Hi,
I am not sure what u intend to do, but in the second for loop you are incrementing variable i rather than j.

Thanks,
gsi.

You code does not use a loop to print temp.
