Count from 10 to 0 to 10

Write your question here.

  #include <iostream>
#include <windows.h>
using namespace std;

int main()
{
 int a=10;

    while(a>=0)
    {
       cout<<a<<",";
       --a;
        Sleep(1000);

    }
    while(a=0,a<=10)
  {
      cout<<a<<",";
      ++a;
      Sleep(1000);
  }

It counts fine until 0,then it won't work.Can you help me?

#include <iostream>
#include <windows.h>
using namespace std;

int main()
{
	int a=10;
    while(a>=0)//10,9,8,7,6,5,4,3,2,1,0
    {
       cout<<a<<",";
       a--;
        Sleep(300);

    }
    a=1;
    //bring a=1 from while loop to outside where it does not repeat, solves the problem
    //start from a=1, if not, two zeros will come out
    while(a<=10)
	//1,2,3,4,5,6,7,8,9,10
	//if you were to use while(a=1,a<=10), every time while loop repeats, a=1, creating infinite loop
	{
    	cout<<a<<",";
    	a++;
    	Sleep(300);
	}
}
