    hello, my code give me run time error each time can you help me?

    void sort_by_area(triangle* tr, int n) 
{
    int S[n-1];
   for(int i = 0 ; i < n ; i++)
    {
     int p = (tr[i].a + tr[i].b + tr[i].c)/2;
     S[i]=sqrt(p * ( p - tr[i].a ) * ( p - tr[i].b ) * ( p - tr[i].c ) );  
    }
    
    for(int i = 0 ; i < n ; i++ )
    {
      for (int j = 0 ; j < n ; j++ )
      {
        int tempS;
        triangle* temptr = tr;
        if ( S[j] > S[j+1] )
        {
          tempS = S[j];
          *temptr = tr[j];
          S[j]=S[j+1];
          tr[j]=tr[j+1];
          S[j+1] = tempS;
          tr[j+1] = *temptr;
  
        }
      }
    }
    
    
}
