Guessing strings non-recursively

How does manipulation of a char array cause a stack overflow?

Why my char pointer do not store the value?

QUESTION

Guessing strings non-recursively

Asked 2021-May-07 at 19:01

I am making a Swift program to stress test certain pieces of computer hardware for a research project I am working on. One of the programs I am making is guessing a password. I currently have an implementation that works by doing it recursively.

Issues with your versions

The problem with your recursive version is that the limits on stack size are quickly reached due to its elementary approach and the combinatorial explosion.

The algorithm works with a depth first exploration, and relies on the backtracking the recursive call allows: once you have reached a dead-end (no more letter to add and string not guessed), you return, and the previous level of recursion starts with the next combination restarting from previous guess.

By the way, instead of using exit you could make your function returns a boolean that would be true if the right combination is found. This would allow to gracefully return recursively instead of loosing time to explore all the other possibilities.

In your iterative guessing version, you only have one guess and only add letters to it, but if you have reached a dead-end, you do not backtrack (or just by one letter). This is why you explore only a small part of the possibilities.

How to make an iterative version

If you want to transform a recursive exploration of string combinatorics into an iterative one, you need to use a queue. Here is how a string guessing function could look like:

QUESTION

How does manipulation of a char array cause a stack overflow?

Asked 2018-Nov-09 at 20:17

If there is a blatantly obvious flaw, I'm sorry. I'm fairly new to memory, so I have some understanding on how stack overflows work and as far as I know, nothing I'm doing should cause a stack overflow. All I'm doing is changing the character in a string.

I know arrays are pointers, but would changing the value cause a stack overflow?

Here is the concerning function:

Your code is iterating over all strings of length 5 made up of the alphabet a-z. This is not a problem by itself, however you have to make sure that the maximal call depth is not too large.

In each iteration of changeLetters you are increasing at most one letter once and then call again to changeLetters and you make at most one such call.

Therefore your call graph is completely linear, for each of the 26^5 strings you are making another recursive call in depth and so the call stack at the end will be about that large. The problem is, that this is a very large number 26^5 = 11881376 and may easily be larger than the stack space you may use.

You need to make the linear call graph into one with branches, by e.g. using a loop over the current character's position instead of calling changeLetters each time.

arr[n] = pass[i];//I m stuck here,it does not assign the value  
n++;
printf("%s %d %d %p %s\n",attempt,i,n,arr[n],pass[i]);
