2 dimensional strcpy err

[Ross]

char chain[10][300];


strcpy(chain[i+20], chain[i]);


error C2664: 'strcpy' : cannot convert parameter 1 from 'char' to 'char *'
Conversion from integral type to pointer type requires
reinterpret_cas t, C-style cast or function-style cast


how to amend that?

Re: 2 dimensional strcpy err

strcpy((char*)c hain + 300*(i+20) , (char*)chain + 300*i);

First thing I would try to do in your case would be to invoke your
compiler in C and not C++ mode. Second, you should make sure that
you don't use array elements that don't exist. With the above 'i'
would have to be between -20 and -11 in order not to access an
element outside of the 'chain' array for the first argument to
strcpy(), but, on the other hand, 'i' has to be between 0 and 20
for the second argument - which it obviously can't be both at the
same time.

Use a C compiler. You are using a C++ compiler. If your product claims
to compile both C and C++, then it has different ways of invoking it for
the two different languages. Read the documentation.

As others have mentioned, you should invoke your compiler in C mode
rather than C++ mode, but I don't think that's your problem.

The first argument to strcpy is of type char[300], which is converted
to char*. The compiler is saying that it's of type char. The only
explanation I can think of is that the code you posted isn't the same
as the code you're trying to compile.

If you post a code sample, you need to cut-and-paste the *exact* code;
we can't guess what your actual code looks like.

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

There are so many things wrong with this post that I'm not even going
to try to correct them.

To anyone reading this post: DON'T DO THIS.

First of all, be sure you are using a C compiler. The file extension
should be .c (lowercase) and not .cpp or .C (uppercase).

First of all - post real code. The code you provided cannot result in
the above error message.
