C++ queue

[mloone01]

Hi,
I am using the following code to create a FIFO queue.

#include <queue>

queue<int> tx_queue;

tx_queue.push(i);

On compiling the vode I get the following error:

'queue' : undeclared identifier

I thought this was declared in #include <queue>. I do not see where the problem is. Any ideas?

All STL stuff resides in the std namespace, so you either have to fully qualfiy the type name like std::queue<int> or use the the using directive using namespace std.
