 1. Study the file `ethernet_hdr.h`. This file contains the definition of the data structure that represents an Ethernet header.:
 
-     #define ETHER_ADDR_LEN 6
+         #define ETHER_ADDR_LEN 6
 
-     struct sniff_ethernet {
-        u_char  ether_dhost[ETHER_ADDR_LEN];    /* destination host address */
-        u_char  ether_shost[ETHER_ADDR_LEN];    /* source host address */
-        u_short ether_type;                     /* IP? ARP? RARP? etc */
-     };
+         struct sniff_ethernet {
+            u_char  ether_dhost[ETHER_ADDR_LEN];    /* destination host address */
+            u_char  ether_shost[ETHER_ADDR_LEN];    /* source host address */
+            u_short ether_type;                     /* IP? ARP? RARP? etc */
+         };
      
 
      The Ethernet header above is used to decode the ethernet part of the raw data in each packet.  It is composed of the source MAC address (ether_shost, 6 bytes), the destiantion MAC address (ether_dhost, 6 bytes), and the type of Ethernet packet (ether_type, 2 bytes) which is used to determine if the packet is an IP packet.
 
 2. The following code is the definition of the class `ethernet_packet`, that can be found in file `ethernet_packet.h`:
  
-     class ethernet_packet
-     {
-
-        sniff_ethernet ethernet ;
-        // Returns a 6 bytes MAC address in string representation.
-        string mac2string(u_char []) ;
-
-     public:
-        ethernet_packet();  // Default constructor
-
-        // Set the ethernet variable member ether_dhost to the values
-        // received in the array
-        void setEtherDHost(u_char []) ;
+         class ethernet_packet
+         {
+            sniff_ethernet ethernet ;
+            
+            // Returns a 6 bytes MAC address in string representation.
+            string mac2string(u_char []) ;
+
+         public:
+            ethernet_packet();  // Default constructor
+
+            // Set the ethernet variable member ether_dhost to the values
+            // received in the array
+            void setEtherDHost(u_char []) ;
         
-        // Same as above but to the ether_shost
-        void setEtherSHost(u_char []) ;
-
-        // Set the ethernet type to the value received.
-        void setEtherType(u_short) ;
+            // Same as above but to the ether_shost
+            void setEtherSHost(u_char []) ;
 
-        // returns the string representation of the ethernet addresses
-        string getEtherDHost() ;
-        string getEtherSHost() ;
+            // Set the ethernet type to the value received.
+            void setEtherType(u_short) ;
 
-        // Return the ethernet type
-        u_short getEtherType() ;
+            // returns the string representation of the ethernet addresses
+            string getEtherDHost() ;
+            string getEtherSHost() ;
 
-     };
+            // Return the ethernet type
+            u_short getEtherType() ;
+         };
 
      Note that each object of the class `ethernet_packet` only has one attribute: a structure of type `sniff_ethernet` named `ethernet`
