any help,, please with explanation

5. This problem considers a linked list that has been created in memory. (15 points total) We know the linked list consists of 4 nodes, starts at address 0x0403130, and has the following declaration in the C code struct Inode ( char *firstname char "lastname; struct Inode *next;) We decide to look at the memory a bit before the beginning of the linked list (gdb) x/40x 0x004030a0 04 0300: 0x4030b0: 0x4030c0: 0x4030d0: 0x4030e0: 0x4030f0: 0x403100: 0x403110: 0x403120: 0x403130: 0403|40: 0x403150: 0x403160: 0x403170: 0x403180: 0x0000000000000000 0x6e6f737265646e61 0x0000000000000000 0x00000000004030fo 0000000000403070 0x0000006563696c61 0x0000000000000000 0x00000a73656e6f 6a 0x0000000000000000 0x0000000000403150 0x00000000004030do 6966 617266 0x0000000000000000 0x0000000a 65706f70 0>'0000000000000000 0x0000000000000021 0x000000000000000a 0x0000000000000021 0x0000000000403110 0). 0000000000000021 0x0000000000000000 0x0000000000000021 0x0000000000000000 0x0000000000000021 0x0000000000403170 0x0000000000000021 0x0000000000000000 0x0000000000000021 0x0000000000000000 0), 0 0 0 0 0 0 0 0 0 0 0 2 081 a) Label in the memory dump where all of the fields of the structure are for the node starting at address 0x0403130.
