Weird, won't let me declare....

OK, I included these files:

Code:

#include <windows.h>
#include <vector>
#include <cstring>
#include <fstream>

I'm using Dev-C++, and I tried to declare a vector, an iterator for the vector, and a string like this:

Code:

vector<string> messages;
vector<string>::iterator forward;
string vtext;

Now, for some reason, I get these stupid errors:

Code:

9 C:\TS.cpp `string' does not name a type 
10 C:\TS.cpp `vector' undeclared (first use this function)

Then more errors saying that messages, forward, and vtext are not declared. Why would it do this?? I have used vectors before and used strings many many times. This is ridiculous, it will probably turn out to be something stupid. Well, thanks for any help.

For string types, you need to include <string>. <cstring> contains functions for null terminated character arrays, i.e cstyle strings.

You also need some kind of using declaration for the std namespace, e.g.

using namespace std;

By the way, did you know a string is an STL container?

Code:

#include<iostream>
#include<string>
#include<algorithm> //reverse()

using namespace std;

int main()
{

	string str = "hello world";
	
	reverse(str.begin(), str.end());
	
	cout<<str<<endl;
	
	return 0;
}

Yes, I knew that type string was in the std namespace. I found the problem, it was something else that affected it. Thanks.
