论坛: 编程破解 标题: 还劳286再来看看(十进制的循环移位的问题) 复制本贴地址    
作者: sniper167 [sniper167]    论坛用户   登录
循环移位，n>0向右移n位，n<0向左移n位
如15896。向右移二位，变为96158
        向左移二位，变位89615


main()
{unsigned long number;
int n;
printf("please input the number and n:\n");
scanf ("%ul,%d",&number,&n);
if (number<10)  {printf("input error!");getch();exit();}
if (n>0)  {printf("number=%d      Move rightwards of %d\n",number,n);
            right(number,n);
          }
else  {printf("number=%d      Move leftwards of %d\n",number,n);
        left(number,-n);
        }
getch();
}


void right(unsigned long value,int n)
{int k,i;
unsigned long m;
m=value;
k=1;
while(m>=10)
  {k*=10;
    m=m/10;
  }
for (i=1;i<=n;i++)
  {value=value/10+(value-value/10*10)*k;
  }
printf("Now,number=%ul\n",value);
}


void left(unsigned value,int n)
{int k,i;
unsigned long m;
k=1;
m=value;
while(m>=10)
  {k*=10;
    m=m/10;
  }
for (i=1;i<=n;i++)
  {value=(value-m*k)*10+m;
  }
  printf("Now,number=%ul\n",value);
}



错误 yiwei.c 18: 与'right'声明中的类型不匹配
错误 yiwei.c 34: 与'left'声明中的类型不匹配

想请286指点,还有没有更好的算法?怎样解决不匹配的错误?
谢谢!

unsigned long number;
if (number<10)

两句矛盾了。既然是无符号，则全是正的。
