用C语言编的两个小小程序

#include <stdio.h>
unsigned int a[11];
int n;
void init1()
 {int i;
  printf("input n(2--10):");  scanf("%d",&n);
  for (i=1;i<=n;i++)
    {printf("input No.%d Number of stone:\n",i);
     scanf("%d",&a[i]);}
 }
void status()
 {int i;
  printf("Now remainder:\n");
  for (i=1;i<=n;i++)  printf(" No.%d   rem: %u \n",i,a[i]);
 }
unsigned int sum1()
 {unsigned int s; int i;
  s=0;
  for(i=1;i<=n;i++)  s+=a[i];
  return s;
 }
unsigned int xorall()
 {unsigned int s; int i;
  s=0;
  for (i=1;i<=n;i++)  s^=a[i];
  return s;
 }
main()
 {unsigned int t;
  int i,s,e;
  init1();
  while (sum1())
   {if (xorall()==0)
     {for (i=1;i<=n;i++)
	     if(a[i]>0)
	       {printf("computer take 1 from No.%d \n",i);
	        a[i]--; goto loop2;}
           }
        else
          for (i=1;i<=n;i++)

             if (s>0)

      loop2:;
      if(sum1()==0)

      status();
      while (1)

  }
 }
