concatenation operators

[artooro]

I'm coming from PHP into the world of C++ and there is one simple thing
I always did:
$othervar = " with another.";
$var = "My string" . $othervar;
output: "My string with another."

Now in C++ you can do this:
char* var "My string" " with another.";

But you cannot do this as you can in PHP:
char othervar [] " with another.";
char* var = "My string" othervar;
I have used strcat() but isn't there a better way?

Use 'std::string' which has operator + defined for it. Do not use
bare pointers to char.

#include <string>

/* and later */

std::string othervar=" with another.";
std::string var="Mi string"+othervar;

There are better ways to do it, but this one is the one you will
recognize more easily

Yes. Use std::string. Look it up in any C++ reference of your choice,
e.g., Stroustrup's _The C++ Programming Language_ (3rd Ed.). Here's an
example:

#include <iostream>
#include <string>
using namespace std;

int main()
{
const string s1 = "some string";
const string s2 = "some other string";
const string s3 = s1 + " and " + s2; // Concatenate
cout << s3 << endl;
return 0;
}

#include <string>

std::string const othervar = " with another.";
std::string const var = "My string" + othervar;

Can't we get some sort of consensus here........Geez!

Thanks.

I use http://cplusplus.com as a reference but might have missed this
somewhere.

You missed it because, at present, they don't have any coverage of the
STL or strings. I'd suggest you get a book if you want a tutorial:
Stroutrup's _The C++ Programming Language_ (3rd ed.), Lippman et al.'s
_C++ Primer_ (4th Ed.), Josuttis' _The C++ Standard Library: A Tutorial
and Reference_, or Koenig and Moo's _Accelerated C++_. They're more
complete than the online source, and chances are your local library has
at least one of them.
