string concat

Hey,

I'm trying to concatenate strings with const chars (letters in the double quotes). I've tried using the + way, the sprintf, and strcat. None work... An example piece below...

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main ( int argc, char *argv[])
{
    string word1 = "this is a string";
    string word2;

    word2 = "hello" + word1 + "\n";

    return 0;
}

---

***not my actual code, it's just extremely similar to it***

That's what I'm trying to do... can anyone help (i don't want to use c-strings)

Thanks in advance,

How about something which compiles first?

I don't know if that'll compile, I just wrote it because my code is long, this is just short and simple. Should be almost the same thing though. trying to do string += "text" + anotherstring;

There's nothing wrong with the code you currently have posted. Why do you think it doesn't work?

If you do "some" + "text" where you have back to back string literals, it might not work, but that's just a guess of a common problem.

Fixed - code I had was bad in many ways :(

spaces_left is an int. You can't add an int to a string with operator+.

What you want to use is a stringstream. Then you can concatenate everything together with operator<< and get the string from it when you are done.
