C Interview Questions and Answers

 

Does C have an equivalent to Pascals with statement?

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;
