随机分配座位，共50个学生，使学号相邻的同学座位不能相邻

随机分配座位，共50个学生，使学号相邻的同学座位不能相邻(早些时候用C#写的，没有用C改写）。
static void Main(string[] args)
{
int Tmp = 0, Count = 50;   
int[] Seats = new int[Count];   
bool[] Students = new bool[Count];
System.Random RandStudent=new System.Random();
Students[Seats[0]=RandStudent.Next(0,Count)]=true;
for(int i = 1; i < Count; ) {
     Tmp=(int)RandStudent.Next(0,Count);
     if((!Students[Tmp])&&(Seats[i-1]-Tmp!=1) && (Seats[i-1] – Tmp) != -1) {
   Seats[i++] = Tmp;
Students[Tmp] = true;
  }
}
foreach(int Student in Seats)
     System.Console.Write(Student + ” “);
System.Console.Read();
