will this work??

hey
is anything wrong with this program???

int *array(int n){
return new int(n);
}
int main(){
int *p = array(10);
for( int i = 0; i < 10; i++ ) {
p = 0;
}
printf( "%d\n", p[0] );
p = array(10);
printf( "%d\n", p[0] );
return 0;
}

Yes. It's not C.

int *array(int n){
return new int(n);

And here's the non-C construct.

}
int main(){
int *p = array(10);
for( int i = 0; i < 10; i++ ) {
p = 0;
}
printf( "%d\n", p[0] );
p = array(10);
printf( "%d\n", p[0] );
return 0;
}

 

[Gordon Burditt]

is anything wrong with this program???

Yes. There is no 'new' in C.

int *array(int n){
return new int(n);
}
int main(){
int *p = array(10);
for( int i = 0; i < 10; i++ ) {
p = 0;
}
printf( "%d\n", p[0] );
p = array(10);

The above line causes a memory leak (except for the problem that it
shouldn't compile in the first place). You have allocated memory
and then throw away the last pointer to it.

printf( "%d\n", p[0] );
return 0;
}

does it matters if its c or c++??
ok consider it as c++..

Does *what* matter?

You need to provide context when posting a followup. Don't assume
that your readers have seen the parent article. See

ok consider it as c++..

This is comp.lang.c; we don't discuss C++ here. Finding a newsgroup
where they do is left as an exercise.

It does in comp.lang.c.

We don't discuss C++ here. is three doors down the
hall on the left, past the water cooler.

If you want to discuss c++, go to a newgroup where it is topical.

Yes.

int *array(int n){
return new int(n);

^^^^^^^^^^^^^^^^^
Syntax error. No reason to go further (unless it's to comp.lang.c++
where they may like this C syntax error).

}
int main(){
int *p = array(10);
for( int i = 0; i < 10; i++ ) {

^^^^^^^^^
I hope your C compiler is one for C99, else this is a syntax error.

p = 0;
}
printf( "%d\n", p[0] );

^^^^^^^^
Using a variadic function with no prototype in scope is a naughty thing
to do.

p = array(10);
printf( "%d\n", p[0] );
return 0;
}

Then it is off-topic in comp.lang.c. We don't answer questions about
how to program in Algol, Fortran, or Cobol either.

Yes. It won't compile as C90, as C99, or even (off-topically) as C++.

My suggestions? (a) decide on a language, and then (b) learn it.

u guys making issue
anyways i will post in c++ grp..
u guys better have invested time in solving problem
enjoyy

Good. Problem solved.

Please quote context and refrain from meaningless abbreviations like
'u', 'grp' etcetera. If not, you're unlikely to get helpful responses
in comp.lang.c++.

Since we are discussing English, it is 'et cetera'. Two words.

OK, That is not an authoritative source. Finding the authoritative
source is left as an exercise to the other pedantic residents of clc.

Have a nice day,

The intention in warning the poster was a genuine interest in help him
reach the maximum possible audience for his posts, since many
otherwise potentially helpful posters ignore, or post unhelpful
replies, to posts containing such "abbreviations." I any case it
wasn't meant as an attempt at demonstrating pedanticism.

No, he didn't. We were discussing English, not Latin. (He is, however,
correct that 'et cetera' comprises two words rather than one.)

It's 'pedantry', not 'pedanticism'.

I realized that. I consider being pedantic a good quality in a place
like this. It is one of the reasons why I lurk here. That and the
occasional dry humor. I guess I should've added a smiley to my post.


<OT about humor>
There is a regular poster who advised a certain researcher at Bell
labs about what is topical in clc. There were a lot of people who were
humor impaired and the resulting flames were very colorful.

Have a nice day,
