c++ - how do i store and get a queue of structure? -


How can I store and obtain the value of the structure in a row where I have 2 values? I want to quote some of these values.

| 4, 2.

| 3, 5.

Where a variable can be from 4,2 and 3,5 such as

  primaryQ.push (a, b);  

My structure:

  struct primarytemp {double process; Double secondary; };  

Here's how I declared my main:

  int main () {queue & lt; Primarytemp & gt; PrimaryQ; Primary Q.push (4, 2); }  

You just type a primarytemp object, type Without modifications:

  Qi < Primarytemp & gt; Q; Q.push (Primetime {4., 2.}); // Existing C ++ standard (C ++ 11) priorityEmpep P = {3., 5} is required; Q.push (p); // PreC + 11 11 works  

As mentioned by other people, you can add a constructor for primitiv , though This means that it is no longer this altogether, it can not be the priority or the case altogether.

primarytemp {}: process (), secondary () {} primarytemp (double process, double secondary): process (process), secondary (secondary) {} dual process; Double secondary; };

This allows you to say

  q.push (primarytemp (4., 2.)); // also works with pre-C ++11  

, use the back () method to push the element that you just pushed , Which gives the reference:

  std :: cout & lt; & Lt; "Process" & lt; & Lt; Q.back () Process () & lt; & Lt; Std :: endl; You can also make a copy of that element:  
  primarytemp = q.back ();  

The front () method allows you to do this with the first element in the queue.

To remove element in front:

  q.pop ();
