Hello all Question about Vector

Does anyone use linux g++? If so i tried to declare a vector and it fails. Saying function is undeclared ususaly meaning the function is is either diffent from the ones i learned and the books i have read in the past or what, but here it is.

Code:

---

//// creates a empty Vector Container
vector<int> Can;

---

Now I just wanted to create a empty one just so i can define it later.

But it keeps giving me function needs to be declared.
In my windows compiler or Bloodshed i used to use both its #include <vector>

and i did the same here to be included so Im clueless hopefully someone has used g++ before.

Also i have done it this way

Code:

---

vector <int> Can

---

You know spacing it away from the word vector

have you #include<vector>??

std::vector<int> Can;

std::vector<int> Can;
or
using std::vector;
vector<int> Can;
or, if you absolutely must
using namespace std;

Bloodshead in windows uses g++, just like stock linux, though you might have a very old version.

yea it was a old verison and all. Thanks guys this board seems to be alot faster it always springs to action so far lol. Whoa thanks guys.

I just downloaded the newest verison.
gcc-3.3.2

Thanks guys

P.S i did std:: on my old compiler and thats what the problem was. So thanks :) ill just use

using namespace std; so i wont have to repeat it.

Thanks :D

Why not get in the habit of using std:: ? If you always use that, and you get used to the look of it, then you won't have to worry about it again. If you use the using namespace std; method, then later when you start having bigger projects you'll find reasons why that might not be a good idea. In the long run it might be easier to make std:: a habit now.

Anyway, its no big deal, just something to consider.
