自己开发的c0文法编译器

const a=1,b=2;
int x,y;
void main()
{
  int i,j;
  scanf(x);
  if(x <= 0)
  {
    printf("Fibonacci of ",x);
    printf("is not exist");
  }
  else if ( x == a )
  {
    printf("Fibonacci of ",x);
    printf("is 1");
  }
  else if(x== b)
  {
    printf("Fibonacci of ",x);
    printf("is 1 2");
  }
  else
  {
    i=a;
    j=b;
    printf("Fibonacci of ",x);
    printf("is 1 2");
    while(x>2)
    {
      y=i+j;
      i=j;
      j=y;
      printf(" ",y);
      x=x-1;
    }
  }
}
