Answer 1

@wio

Answer 2

It looks like your pointer is pointing at an address that is before the actual beginning of the string.

Answer 3

so what would i pass in gdb?

Answer 4

I think the problem fundamentally is the pointer but...

Answer 5

Answer 6

try using `(&puzzle + 20)` and see what you get

Answer 7

`(&puzzle1+20)`

Answer 8

adress out of bounds

Answer 9

can you give a picture

Answer 10

when i do &puzzle1+5, i get "is watching you"

Answer 11

What about +4?

Answer 12

+3 did the trick.

Answer 13

ok ok, cause it was 8 bytes from T to i. ok ok.
thank you! nice hint!

Answer 14

I guess the type of puzzle1 isn't a char, because the pointer arithmetic is moving it far.

Answer 15

it looks like it's a type that takes 4 bytes.

Answer 16

32 bit, could be an integer or something

Answer 17

Alternatively, you could have done something like `(((char*) &puzzle1)+12)`.
