Don't know!!! But ....

I can tell you that I use SciTE as my go-to editor! Here's the complete output:


>gcc -Os -std=c99 -pedantic test-pointers3.c -o test-pointers3
test-pointers3.c: In...

I've tried that, and although it compiles, I get the same warning:

warning: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘int **’ [-Wformat]

So casting to (void *)...

The following should help me and others:

C Printf and Scanf Reference

I should explain the situation a bit more clearly ....

My original test code was:



#include <stdio.h>

int main(int argc, char *argv[])
{

For example:



#include <stdio.h>

int main(int argc, char *argv[])
{
int x;
int *ptr;

Using the latest gcc incarnation, why wouldn't the following work??


(void) scanf("%d", &blah);

gcc keeps on barfing up the "unused value" warning....

It'll shut up, if I test the return...

Thanks! I'll have to give that a try ....



You bet!! I have that commented out in my code. I had tried it out both ways ...

Thanks for the input!

Does this code that I cranked out give some indication that I'm getting it, or am I just dreaming in Technicolor?



#include <stdio.h>

int main(int argc, char *argv[])
{
int myAge = 65;...

@Bayint Naung


printf(" sum = %d &sum = %p \n", sum, (void*)&sum);

did the trick! Thanks!

Sooo many details to learn for a noob! :) Thanks! I'll flip to the 'casting' section of the tutorial, and add to the growing body of knowledge/frustration? :))

BTW , I bookmarked the above URL....

hey ...

Here's the warning:


warning: format ‘%p’ expects type ‘void *’, but argument 2 has type ‘int *’

Here's the code

C++ Utopia?? :D

OK! OK! I'll burn the Turbo C Manuals - along with all the other OOP detritus that has accumulated in my den over the years. :)

@Bayint Naung

What you say may all be true! I'm not suggesting that I would/want to use Turbo C for production work - just as a learning tool. However, the point is moot! Like I said, I'll most...

FYI - to those who have been following this thread ...

Turbo C v2.01 loads and runs normally on my AMD Athlon XP 2000+ based machine running XP Home. As well, it compiles C code - no probs! The...

I just had a quick "boo" at the Pelles Forum. Seems that joint is overrun with "spuds" too. :)
Thanks for the extra info.

@staha01
I almost sure that Salem is going to jump in and "second" your recommendation! :D Thanks!

@Salem
Your reply here might just have answered my question about using Turbo C (and it's manuals) in another thread :)

Funny thing though - the code compiles under Linux (gcc) with no warnings...

hey ...

I happen to have Turbo C c/w the manuals. Although I'm on *nix 99% of the time, I do have XP on a separate partition. Will Turbo C complicate my C learning process more than help it, in...

Hello list ...

I think I'm grokking it - but please critique the following code and comments therein:

As a former USMC enlistee with his "gold wings", I can say that the first time I jumped out I was scared. The 2nd time, that sorry-ass Jump Master had to push me and a bunch of others out. :)) Dirty...

@Tater
Aaah! Come on! Don't the OOP guys do _that_ all the time? :)

@Tater
Yeh! You're right! Not worth the bother.

I know _some_ C :) I'm fluent in Perl and PHP; learning Ruby at the moment. Can also get by in newLISP. So I'm not totally clueless - but yeh!...
