How To Create Multiple Range-Based For Loops?

[kindgnice]

I am back again... :D
I am trying to figure out if it's possible to implement multiple range-based for loops?

So far, I see the patterns like:

	for (Pt2 p : vertices2)
	{
		cout << "\nVertices2: ";
		cout<< p.x<<" ";
		cout << p.y<<" ";
		cout << p.z<<" \n";

	}

I am thinking if it's also possible to put multiple range-based for loops such as:

	for (Pt2 p : vertices2) & (Pt2 q : vertices2)
	{
		cout << "\nVertices2: ";
		cout<< p.x<<" ";
		cout << p.y<<" ";
		cout << p.z<<" \n";
		cout << "\nVertices2: ";
		cout<< q.x<<" ";
		cout << q.y<<" ";
		cout << q.z<<" \n";
	}

My syntax is bad and not working. I would like to ask the proper way of doing it if it's possible. Thank you for your response in advance. :)

What are you trying to do? Is it this?

#include <iostream>
#include <vector>

int main()
{
    
    std::vector<int> vertices2{1,2,3,4,5};
    
    	for (int p : vertices2) 
       {
           for (int q : vertices2) 
           {
               {

			std::cout<< p << "-" << q << '\n';
                }
           }
           std::cout << " Next p\n";
	    }
}

Thank you very much Mr. Repeater for your response. I overlooked this thread.
I was trying to figure out if it's possible to read and output values in just one loop?
However, since I am not good in programming, what I did was to call them twice just to output separately the values of p and q.
