TURF(开源)权限管理系统

TURF（开源）权限定制管理系统（以下简称“TURF系统”），是蓝水工作室推出的一套基于软件边界设计理念研发的具有可定制性的权限管理系统。TURF系统充分考虑了易用性，将配置、设定等操作进行了图形化设计，完全在web界面实现，程序员只需在所要控制的程序中简单调用一个函数，即可实现严格的程序权限管控，管控力度除可达到文件级别外，还可达到代码级别，即可精确控制到

• Input the number ‘n’ from user
• Divide the entire pattern into three parts i.e. upper part, middle part and lower part Start loop i for printing the upper part of the pattern from i to 0 and i to be less than n and keep incrementing the value of i Start loop m for printing the middle part of the pattern from m to 0 and m to be less than n-2 and keep incrementing the value of m Start loop h for printing the lower part of the pattern from h to res and h to be greater than 0 and keep decrementing the value of h Keep printing the * with spaces.

ALGORITHM

START
Step 1-> declare function to print hexagonal pattern
   void pattern(int n)
   Declare and set int len = 2 * n - 1
   Loop For int i = 0 and i < n and i++
      declare and set int temp = i + n
      Loop For int k = 0 and k < temp and k++
         IF ((k == n + i - 1) || (k == n - i - 1))
            print *
         End
         Else
            print space
         End
            Print 

      End
      Loop For int m = 0 and m < n - 2 and m++
         Loop For int j = 0 and j < len and j++
            if (j == 0 || j == len - 1)
               Print *
            End
            Else
               print space
            End
         End
         Print 

      End
      declare and set int res = n - 1
      Loop For int h = res and h >= 0 and h--
         declare and set int temp2 = h + n
         Loop For int k = 0 and k < temp2 and k++
            if ((k == n + h - 1) || (k == n - h - 1))
               print *
            End
            Else
               print space
            End
         End
         Print 

      End
   End
Step 2-> In main()
   Declare variable int n = 5
   call pattern(n)
STOP
