       1. Array of Pointers (*mess[]):
          - It stores 4 pointers. 
          - Size of a pointer is typically 4 bytes (32-bit) or 8 bytes (64-bit).
          - Total = 4 * sizeof(char*)
          - Plus the strings themselves are stored elsewhere in memory.
       
       2. Two-Dimensional Array (mess[][]):
          - Must accommodate the longest string ("Hammer and tongs" = 16 chars + null = 17).
          - Width would be 17 (or more).
          - Size = 4 rows * 17 cols * 1 byte.
