螺旋数列多种版本.doc

用VB写出螺旋数字打印的代码:
代码实现在窗体上打印如下列文字的效果:

01 02 03 04 05 06 07 08 09 10

36 37 38 39 40 41 42 43 44 11

35 64 65 66 67 68 69 70 45 12

34 63 84 85 86 87 88 71 46 13

33 62 83 96 97 98 89 72 47 14

32 61 82 95 00 99 90 73 48 15

31 60 81 94 93 92 91 74 49 16

30 59 80 79 78 77 76 75 50 17

29 58 57 56 55 54 53 52 51 18
