Descending C++ Code

The Program will ask you 3 Numbers and it will arrange it from highest to the lowest

here is the code:

#include <iostream>

using namespace std;

int x=2;

int check (int a, int b, int c)

{

    int d=a;

    

    if (x==0) 

    {

              if (b>c)

              {

                     cout<<"\n The highest value of them is = "<<a<<" then "<<b<<" then "<<c<<endl;

              }

              else 

                     cout<<"\n The highest value of them is = "<<a<<" then "<<c<<" then "<<b<<endl;

                      

    

    return(0);

    }

    if (a>b)

    {

            

            x=x-1;

            check(a,c,b);

    }       

    else 

    {

            x=x-1;

            check(b,c,a);

    }

}

int main()

{

      int a,b,c;

      cout<<"First value = ";cin>>a;

      cout<<"\nSecond value = ";cin>>b;

      cout<<"\nThird value = ";cin>>c;

      check(a,b,c);

      

      system("Pause");

      return 0;

}
