Strcpy

[Jake Thompson]

I need to copy a value into a char * field.

I am currently doing this

strcpy(cm8link. type[count],"13");

but I get an error of

error C2664: 'strcpy' : cannot convert parameter 1 from 'const char' to
'char *'

this used to when it was just cm8link.type but it errors when I make it


cm8link.type[count]

first of all why?

secondly how can i get the value into the field for this array
occurrence?

Thanks

Jake

You don't give its declaration, but I bet the above is of type `char`
rather than `char *`.

Please post a small compilable example of your code that exhibits the
problem (and it's output).

We went over this last time. Post a COMPLETE, minimal program that
compiles and demonstrates the problem.

How can we possibly say anything without seeing the declarations of the
variables?

What field? What array? Where's my damn crystal ball?

You don't make easy for us to help you.

Re: Strcpy

First of all I appreciate the help and certainly there is no need to
lash out

Secondly I did say that the field cm8link.type[count] is a char * field

I don't see the need to have the entire program listed. It is a one
line statement that obviously I am using the wrong way.

In a nutshell I need to move a literal to a char * that is part of an
array

currently as an example I am doing the following just so you know count
is normally incremented in a loop but here i set it to clearly define
that I want to move the value 13 into

cm8link.type[2],

int count = 2;

strcpy(cm8link. type[count],"13");

resulting in the error

error C2664: 'strcpy' : cannot convert parameter 1 from 'const char' to

'char *'

But to see how and why you're using it the wrong way, we need to see
the sorrounding relevent source, don't we?

Then figure it out yourself.

Well if it means dealing with a Dick as the alternative then hell yeah
I will figure it out myself.

Thank God your attitude is the minority here.

... but since the compiler contradicted you (it
described the field as `const char'), didn't it occur
to you to offer the actual code so someone could try to
judge whether you or the compiler is in error?

... and the "what's wrong with it" is clearly a
matter of context. Can you tell, without looking at
any of the rest of the program, whether the one line

x = 42;

is right or wrong? (If you think you can, you need to
re-open your C textbook.)

You claim that `cm8link.type[2]' is a `char*', while the
compiler claims it's a `const char'. Without further evidence
it would be injudicious to say which of you is right -- but
I'm forced to disclose, right here on my jury screening form,
that I am more likely to believe the compiler's testimony than
yours. Since I am obviously prejudiced, I won't be empanelled
(a lucky break for you; I'm in a mood to hang uncooperative
witnesses).

This is not a forum to throw mud at each other. Admittedly Default User
was rather curt in his reply, but the point he, I and several others
have made to you still stands, i.e. post the smallest compilable code
that exhibits your problem or failing that atleast post relevant
sarrounding code like data declarations, prototypes etc., so that we
don't have to keep guessing.

Also please quote the post to which you're replying. Most regulars in
this group, access it via nntp servers which might delete articles
after a certain time, unlike Google Groups. Including context makes the
post comprehendable in such cases.

Obviously it's not, as the error says it's a "const char".

The problem is that without seeing the actual definition of
cm8link.type[count], people can only guess as to the "real"
problem. The compiler says one thing, and you say something
else. We tend to believe the error message over your claim
until you show us the compiler is wrong.

An array of what?

But, what type is cm8link.type[2]? What is cm8link.type?

While tells us that cm8link.type[count] is of type "const char", and
not the "char *" that you continue to claim.

Unfortunately, his attitude is the majority here. Certain individuals will
call you off-topic or a troll despite the fact that they've only posted
complaints and have never posted anything C related:

Re: Strcpy

Sorry for my outburst


This is the function that I am calling



char *folderid;
struct cm8linkstruc cm8link; <----------------structure tag set to
cm8link



struct cm8linkstruc
{
char* type; /* type of item*/
<------------------------------------------field that I want to copy
the "13" too
char* desc; /* description of item */
char* item_increment; /*increment value for item
in folder */
char* itemid; /* id of returned item */
};


These are the lines of code that I am trying to execute in order to
copy the values too.

strcpy(cm8link. type[count],"13"); //Copy the number 13 to indicate
folder
strcpy(cm8link. desc[count],"Document "); //copy the description
strcpy(cm8link. desc[count],snumD); //copy the current doc counter to
the description
strcpy(cm8link. item_increment[count],snumD); //copy Document counter
cm8link.itemid[count] = ((DKPidICM*)par t->getPidObject() )->getItemId()
; //Get the itemid

Is this enough information to go off of?

Since you have this problem, it's clear that there's something
about the program that you don't understand. So we can't (and you
shouldn't) trust your judgement as to what is "obvious".

In particular, we can't trust your claim that cm8link.type[count]
is of type char *. Show us the whole program!

You need to provide context when you post a followup. Read
<http://cfaj.freeshell. org/google/>, and you'll understand how and
why.

Upthread, you wrote:

] line statement that obviously I am using the wrong way.

If you already knew what the problem is, then presumably you wouldn't
need to ask for our help.

Conversely, the fact that you *are* asking for our help implies that
you really don't know what the problem is. If we offer you advice on
what information *we* need to help you solve *your* problem, then you
really should pay attention. We're not making you jump through hoops
just for the fun of it; we're asking you to help us to help you. If
you're unwilling to do so, then we can't help you.

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

As you can't be bothered to follow simple instructions when you're the
one wanting help, plus you refuse to quote any context, it's pretty
obvious what happens next.
