597: Mainline 
 

Assembling the type specifications and parameters into main, you 
have the following demonstration program, which just displays the name of 
the program and the argument, which is presumed to be a  
 
 
file specification: 

#include   
main (int argument_count, char **argument_array) { 
  printf ("You have supplied %s to %s.\n", 
                             argument_array[1], 
                                   argument_array[0]); 
} 

 
Accordingly, if the name of the demonstration program is 
demonstration_program and you type the command line 
demonstration_program file_name.extension, you obtain the following 
result: 

You have supplied file_name.extension to demonstration_program.
