-So, the address of the `main` function is the `0000000000400506` and it is offset from the `.init` section. As we can see from the output, the address of the `factorial` function is `0x0000000000400537` and binary code for the call of the `factorial` function now is `e8 18 00 00 00`. We already knwo that `e8` is opcode for the `call` instruction, the next `18 00 00 00` (note that address represented as little endian for the `x86_64`, in other words it is `00 00 00 18`) is the offset from the `callq` to the `factorial` function:
