priority_queue<int,vector<int>,greater<int> > q;
printf("%u",q.size());

打这个总是出现警告

[Warning] format '%u' expects argument of type 'unsigned int', but argument 2 has type 'std::priority_queue<int, std::deque<int>, std::greater<int> >::size_type {aka long long unsigned int}' [-Wformat=]

请问怎么打才能弄掉这个警告。
