Understanding Memory Management, Part 1: C

i am no C programmer, but doesnt the first pseudocode make no sense (and others after since they reuse it)?

  address = X
  length = *X
  address = address + 1
  while length > 0 {
    address = address + 1
    print *address
  }

1) length is never updated so while is infinite loop (if length is not 0)

2) the first character is never output since at address 0 (assuming X=0 at the start) is the value length but then the pointer is incremented twice so the first print *address prints the character at address 2?

if I am mistaken I'd be happy if someone explained why it makes sense
