reverse string, how to print string and not decimals?

[ssecorp]

char* reverse(char* str) {
int length = strlen(str);
char* acc[length];
int i;
for (i=0; i<=length-1; i++){
acc[length-1-i] = str[i];
}
return acc;
}

How do I then print a string and not decimals? If I add printf inside
the for loop it prints decimals. they are reversed so it works but I
want to prin chars.

Show us the code. There is no printf() in what you have.

acc is an array of pointers to characters. Are you /positive/ that this is
what you want. I don't think it is.

int i;
for (i=0; i<=length-1; i++){
acc[length-1-i] = str[i];
}
return acc;

Are you /certain/ that you want to return an array of pointers to
characters? Wouldn't you rather return a single pointer to a character?

}

Huh?

If I add printf inside the for loop it prints decimals.

Then you did it wrong. In any case, it makes no sense to put a printf()
inside your reversal loop.

they are reversed so it works but I want to prin chars.

Yes? So?

First off, correct your string reversal function. You want something like...

char *reverse(char *str)
{
char *start, *end, temp;

for (end=str;*end;++end); /* point end at end-of-string */
--end; /* point end at last-character-in-string */
for (start=str; /* point start at first-character-in-string */
start < end; /* loop until start passes end */
++start, --end) /* move start up, end down */
{
temp = *start; /* save the character at start */
*start = *end; /* put character at end into place at start */
*end = temp; /* put saved start character into place at end */
}
return str; /* return pointer to first character */
}

Then, you can do something like...

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
char text[] = "This is a test";

printf("Normal: \"%s\"\n",text);
printf("Reversed: \"%s\"\n",reverse(text));

return EXIT_SUCCESS;
}

and see that the reverse() function does indeed reverse any modifiable text
string.

What do you mean by "decimals"? If you're using printf() like
'printf("%d", str[i])', then yes, it will print something like
numbers, since the conversion specification '%d' is for integers, not
for chars. Use '%c', or simply putchar().

Also, your function returns a pointer to a local object, which will be
deallocated when the function returns, and thus what it returns will
point to nothing. What you want is probably a function that modifies
the string "in place."

char* acc[length];

This is problematic for at least four reasons:

a) The size of an array must be a compile-time constant unless
you have a compiler that supports C99 variable length arrays
b) You ask for 'length' pointers to char, but it looks very
much as if you just want an array of chars
c) If 'acc' would be an array of chars it would be too short by
one element if you want to store a string with the same length
as that of 'str' in it (don't forget about the trailing '\0'
char that is needed to make a string out of a mere char array)
d) You later try to pass back a pointer to the array to the caller
but this array is a local variable that vanishes the moment the
function is left and then can't be used anymore.

There are basically two ways you can get aroung the last problem.

1) Have the caller pass a second array to the function in which
you store the reversed string
2) Allocate memory for the reversed string (and tell everyone
that's going to use this function to deallocate it when it's
not needed anymore).

A third approach would be to have a static array that's long
enough for each string you will pass to this function. But there
are two difficulties. First of all knowing in advance what the
longest string that ever will be passed to the function can be
tricky ti say the least. And the reversed string can only be used
between two invokations of the function since the next invokation
will overwrite the previous result.

int i;
for (i=0; i<=length-1; i++){
acc[length-1-i] = str[i];
}

If 'acc' would be an array of chars (of sufficient length) it
now would contain the reversed chars from 'str'. But it's still
missing a trailing '\0' char and thus it's not a string.

return acc;

And that's, as I wrote, absolutely wrong. You can't safely pass
back a pointer to a local variable for use in the caller.

}

How do I then print a string and not decimals? If I add printf inside
the for loop it prints decimals. they are reversed so it works but I
want to prin chars.

No idea what this means. Show your printf() call and you probably
will get an answer. But without knowing what exactly you did there
it's impossible to say.

Due to what is probably the wrong definition of acc, this statement
contains a constraint violation and the compiler must issue a
diagnostic for it. Did yours? If so, why did you ignore it? If not,
either up the warning level or upgrade to a competent compiler.

}
return acc;

You need to tell us what code you executed and how the result differed
from what you want. The fact that you used printf is not sufficient.
Show us the exact code.

I think the point is that the quote markers clearly indicate that you
did not write the "char* acc[length];" line, despite "Mark B

wrong one. So it was, strictly speaking, unnecessary for you to respond

I have no idea what you want, but here is something you can look at:

#include <stdio.h>
#include <string.h>
static char*
reverse_in_place(
char* const buf

char* spos = buf;
char* epos = spos + strlen(spos) - 1;
for (; spos < epos; ++spos, --epos) {
char const tmp = *spos;
*spos = *epos;
*epos = tmp;
}
return buf;
}
static void
fprint_without_char(
FILE* const out,
char const* buf,
char const strip

for (; *buf; ++buf) {
if (*buf != strip || strip == '\0') {
fputc(*buf, out);
}
}
}
int main() {
char data1[] = "\nsdoirep tuohtiw - ...1 .rev .gnirts .esrever";
char data2[] = "\nsdoirep htiw - ...1 .rev .gnirts .esrever";
fprint_without_char(stdout, reverse_in_place(data1), '.');
fprint_without_char(stdout, reverse_in_place(data2), '\0');
return 0;
}
__________________________________________________ ______________

You can reverse the strings and get the output to strip out the periods via
the `fprint_without_char()' procedure...

It wasn't hard to tell when the thread only had
2 posts on it, much has happened since though.

but I don't think it

Fairly obvious that the printf() statement was inserted for
debugging purposes and does not belong in the completed
code.

Frankly there more debates on topicality than there should be, but I
don't see any resolution, as different participants hold entrenched
views.

Personally I only object to repeated off-topic posts even after the
concerned poster has been told of the presence of better groups to
serve his purpose. Newbies posting off-topic questions are natural,
since they cannot be expected to know the topicality constraints of
this group even before their first post.

However, there are some here who object to *any* redirection, no matter
how off-topic the post. IIRC one of the so-called trolls even wanted to
deliberately discuss hardware issues here.

What is this "some of the time"? There are precious few folks in my

Except that it formed the basis of what he asked. At any rate, it was
clear he was asking about a different program than the one he posted.
So I didn't waste my time on it, anymore than a mechanic takes a look
as similar car to the one that's malfunctioning.

What the hell do I care what trolls think or do? We should refrain from
posting because the trolls might respond? If you choose not to plonk
trolls, that's not exactly my responsibility.

Something nobody has mentioned yet (despite
there being 47 replies already) - you try to
return the address of a local array, that
will no longer exist once the function returns.

If you want to return a string then you will
have to be more careful about allocating
memory for it.

Hey! I know you!

Might want to read a few of those 47 replies...
it's been mentioned numerous times ;-)

True, I skipped over half of the thread
where it looked like everybody was
bickering about irrelevant crap.

Fairly obvious that the printf() statement was inserted for
debugging purposes and does not belong in the completed
code.

OMFG, you don't let up!

Just persistent that way! It helps being right and all.

Weren't you supposed to be "done with me"?
