}

bool Contenedor::insertarPos(int pos, int ele){
	if (pos>Cantidad)
	{
		cout << "No hay espacio para insertar!" << endl;
		return false;
	}
	else {
		//Scan to da right.
		int y = 1;
		cout << "Insertando valor: " << ele << ", en la posicion: " << (pos + 1) << "." << endl;
		int temp = Vector [pos];
		int temp2 = Vector[pos + y];
		
		
		for (int i = 0; i < Vector[pos]; i++)
			
			Vector[pos] = ele;
			Vector[(pos + y)] = temp;

			y++;
			Cantidad++;
			
			Vector[pos + y] = temp;
			Vector[pos + y] = temp2;
			Vector[pos + (y + 2)];
			y++;
			
					
		}
}


At this point, you can see when compiled that, the last value isnt showing up. Also, i find my code extremely un efficient so i would like to know if it would work if i keep entering new values. Can you tell. Thanks a lot for your time, friends.

Note that vector has insert() member function: http://www.cplusplus.com/reference/vector/vector/insert/
So your code can be rewritten as:
1
2
3

bool Contenedor::insertarPos(int pos, int ele){
	if (pos>Cantidad) {
		cout << "No hay espacio para insertar!" << endl;
		return false;
	}
	Vector.insert(vector.begin() + pos, ele);
	return true;
}

Yes, MiiNiPaa, thanks a lot, im aware of that but theyre asking to use For !

	Vector.push_back(ele);
	int last = Vector.size() - 1;
	for(int i = pos, i < last; ++i)
		std::swap(Vector[i], Vector[last])
	return true;
