Why doesn't std::queue support a clear() function?

Question

I have requirement: for a function, I get the input as a stream of numbers. I mean, the function keeps on getting called with single number in each call. I am using std::q

Apart from what has been said already, you can clear a queue very easily:

queue q;
...
q = queue(); // Assign an empty queue

or in C++11

q = {};
