This is probably better suited for Stack Overflow.

It looks like you're coming from some other language. Try this instead.

$ cat test.c
#include <stdlib.h>

struct loopy
{
  int i;
  char* ptr;
};

int main(int argc, char* argv[])
{
  struct loopy loops[] =
  {
     {0, "LLVM"},
     {0, NULL}
  };

  for (struct loopy* ptr = loops;
       ptr->i < 10 && ptr->ptr != NULL;
       ++ptr)
  {
      /* ... */
  }

  return 0;
}

$ clang test.c -o test.exe
$ ./test.exe
$
