Priority Queue :: C++

Hi.

Visual C++ .NET outputs this error when I try to declare a priority queue with reverse sorting.

-----
// Assuming program runs and before I added the following.
#include <queue>
#include <functional>

std::priority_queue<int, std::greater<int>> m_nQueueList;

// I try this declaration, but receive the exact same
// error everytime.

std::priority_queue<int, std::vector<int>, std::greater<int>> m_nQueueList;
-----

Here is the error from Visual C++ .NET

-----
C2065: 'm_nQueueList' : undeclared identifier
error C2143: syntax error : missing '>' before ';'
error C2146: syntax error : missing ',' before identifier 'm_nQueueList'
error C2208: '<Unknown>' : no members defined using this type
error C2947: expecting '>' to terminate template-argument-list, found '>>'
error C2976: 'std::priority_queue' : too few template arguments
-----

Does anyone know what the problem is?

Thanks,

Code:

---

std::priority_queue<int, std::vector<int>, std::greater<int>> m_nQueueList;

---

does this '>>' look familair? It is being parsed as the left shift operator. You need a space between the two brackets.

Code:

---

std::priority_queue<int, std::vector<int>, std::greater<int> > m_nQueueList;

---

when u post code use the code tags like
(code)
your code here
(/code)

but instead of ( and ) put [ and ]

Okay. Thanks.

Added a space in between ">>" fixed it.

Here is the working solution.

Code:

---

std:riority_queue<int, std::vector<int>, std::greater<int> > m_nQueueList;

---

I would have never guessed the problem had to do with a missing space. That space operator is tricky.
