After read a whole OS written by C, someone asks `What is the advantage of C'

[lovecreatesbeauty]

After read a whole OS written by C (e.g. UNIX 6th Edition written by),
at the end (yes, at the last line of the text of the last chapter),
someone (sure, it's John Lions) asks `What is the advantage of C' (is
it your question also).

Could you rephrase this question, in English this time?

I'll assume he's repeating the question from the text, "What is the
advantage of C" I have to ask compared to what?

I mean C lets you do manual computations easily. But so does any other
language. So without a context listing possible "advantages " is a bit
hard.

I *think* he means the very last bit in 'Suggested Exercises':

6.2 "Discuss the merits of the "C" as a systems programming language. What
features are missing? or superflous?"

Do you have the book handy? Even John did not mention the contrary
language(s).

No I don't. And I suspect many others don't either.

Why don't you provide more context for the question so we can all
participate.

A "with" expression like found in Turbo Pascal would seriously rock.

e.g.

struct mystruct {
int this;
char that;
void *otherthing;
};

// ... code
struct mystruct *p;

with (*p) {
this = 3;
that = 4;
otherthing = "hello world";
}

That'd rock. Specially when dealing with nested structures e.g.

p[4]->this.item[3].value = 3

with (p[4]->this.item) {
value = 3;
key = "hello";
// blah
}

Now granted you can sorta emulate this with a macro, e.g.

#define SETALL2(p, k, v, k2, v2) \
do { \
(p) . k = v; \
(p) . k2 = v2; \
} while (0);

but that's less cool.

There are hundreds, probably thousands, of other programming
languages. C has advantages with respect to each of them, and
disadvantages with respect to most of them.

We must do something. This is something. Therefore, we must do this.

I prefer

#define NEW_SETALL2(p, k, v, k2, v2) \
do { \
(p) . k = (v); \
(p) . k2 = (v2); \
} while (0)

without ';' and with parentheses around 'v' and 'v2'.

In this case you can use the macro as a function call

NEW_SETALL2(p,k ,v,k2,v2);

It means nothing, it's too abstract. Could you go to some specific
facts? Thanks for concern.
