The problem with the display_industry_name approach is that some of the displaying is done inside a subfunction, and some is done with an explicit display statement. A more transparent, orthodox approach is to have a different function, industry_name, return a string, with all the displaying done in the explicit display statement:

/* Display report */ 
for (counter = 0; counter < limit; ++counter)  
  printf ("%s %f %i %f\n", 
          industry_name(trade_pointers[counter]), 
          trade_pointers[counter] -> price, 
          trade_pointers[counter] -> number, 
          trade_price(trade_pointers[counter]));
