Does C use short circuit evaluation even when arguments are function calls?

Question

I know that logical operators do short-circuit checking. That is, if there is a statement like A && B && C, then if A is false,

Answer 1

Yes, the functions are not called if root1->data == root2->data is false.

Simple check is to do this:

#include 
#include 

int main(void)
{
  write(1, "z", 1);
  if ((1 == 0) && write(1, "a", 1) && write(1, "b", 1))
  {
    write(1, "c", 1);
  }
  write(1, "d", 1);
  return (EXIT_SUCCESS);
}
