string variables

Yes, you can.
However, if your target hardware is memory-constrained (which is often the case) you should carefully consider if this is a good idea.

Memory limit is not my problem for now.
You mean that I can write something like:

#include <string.h>

int main()
{ string = "test"; return 0;
}

And compile and link with no errors?

Huh?
What kind of code is that? It doesn't make any sense. Surely you can come up with a working example.

Xmm, sorry my friend,

#include <string.h>

int main()
{ string a= "test"; return 0;
}

And thanks for the fast replay
I am multitasking at job right now.

Still wrong.
The following code compiles without warnings:

#include <string>

using namespace std;

int main(void)
{
        string a = "test";
        return 0;
}

your code returns errors like those:

I don’t know why
Maybe some settings?
My target is cortex m3
Any idea?
andy

Embedded programming is not so easy, eh?
You should start with an example program that closely matches your target hardware. Once you get it to compile and run, you can start making modifications.

If it can be done, this is all I need to know.

A simple thanks is not enough
A honest one is better.
Thanks Mike
