Answer 1

The fun part of this problem is not just getting something to work, but figuring out a clever way to do it. I'm sure there are several solutions, here's mine:

#include <stdio.h>

#include <math.h>

int main(int argc, char *argv[]) {

  int n,i,j;

  char x;

  if ((argc < 2) || (sscanf(argv[1],"%d",&n) != 1)) {

    printf("\nusage: %s <n>\n",argv[0]);

    return -1;

  }

  n = fabs(n);

  for (i = 1; i <= n; i++) {

    for (j = 0, x = i&1; j < i; j++, x ^= 1) {

      printf("%d",x);

    }

    puts("");

  }

  return 0;

}
