Exactly what headers do you have to include to use vectors? i tried putting , and but when i put the following line of code in my program (minus the //): //vector particles; it gives me these errors: C:\Code\Games\CDXDemo\ParticleSys.h(84) : error C2143: syntax error : missing ';' before '<' C:\Code\Games\CDXDemo\ParticleSys.h(84) : error C2501: 'vector' : missing storage-class or type specifiers C:\Code\Games\CDXDemo\ParticleSys.h(84) : error C2059: syntax error : '<' C:\Code\Games\CDXDemo\ParticleSys.h(84) : error C2238: unexpected token(s) preceding ';' this would normally mean that i don't have the required files included but i do.

vector is the file. No extension, just that:


#include <vector>

To use it, you either need to explicity specify the "std" namespace each time, or make an early blanket statement:

Either:


std::vector myVec;

Or:


// Once at beginning of file
using namespace std;

vector myVec;

and beware this forum strips < and > unless you''re in source blocks. Here''s a working sample to get you started:

  
//main.cpp

#include <vector>

using namespace std; // never do this in a header file


int main ()
{
  vector<int> intVec;
  intVec.push_back (42);
  return intVec.size ();
}

(should return 1)
