Thread: Process terminated with status -1073741819

Hi, I use Code::Blocks and I'm writing a program that is supposed to count the number of possible variations between 10 letters of the alphabet. The program compiles, but once I run it, it crashes and gives me this error:

Process terminated with status -1073741819

And I have no clue why is that happening. Here is the code:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void move(char *one, char *two);

main()
{
    char alf[] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'};
    int count, index, max = 0;

    for (index = 9; strcmp(alf[9], 'a') != 0; count++) {
       if (index == 0) {
          index = 9;
          continue;
       }
       move(&alf[index], &alf[index - 1]);
       max++;
    }

    printf("%d", max);

    return 0;
}

void move(char *one, char *two)
{
    int aux;

    aux = *two;
    *two = *one;
    *one = aux;
}

Any help will be welcome.
Thanks in advance.
