Queue. What is the working principle of the push() method?

Question

C++ / C#

There is a structure

struct Process{
  int id;
  int type;
}prcs[SIZEPRCS];

and there is a queue
queue <Process> PR;
when using the method
PR.push(prcs[0]);
I get a new element?

Answer 1

Typically, push adds an element to a container, and pop removes it.

Answer 2

same as, say, push_back on std::vector
