I have to implement the minimum priority_queue using vector<char, int>. I am confused with the following code snippet.

priority_queue(int , vector<char, int> , greater<int> pq;

But this is absolutely wrong.

  • Did you posted the right code because at least a closing paranthese is missing? Please give more details where do you need help. – Martin Zabel Feb 27 '16 at 20:21

This should work : 

priority_queue<int,vector< pair<char, int> >, greater< pair<char,int> > > PQ;

  • What do you mean by that you have not inserted any thing in the priority queue there, you are only inserting things in the vector. – uSeemSurprised Mar 05 '16 at 07:42
