No. The way in C to get quick and easy access to the fields of a structure is to declare a little local structure pointer variable (which, it must be admitted, is not quite as notationally convenient as a with statement and doesn't save quite as many keystrokes, though it is probably safer). That is, if you have something unwieldy like
structarray[complex_expression].a =
structarray[complex_expression].b +
structarray[complex_expression].c;
you can replace it with
struct whatever *p = &structarray[complex_expression];
p->a = p->b + p->c;
