冒泡排序在PB中的实现

 冒泡排序主要是用于把一组数据进行排序，在pb中函数方式实现如下()：

/*-----------------------------------------------------------------------------------------------

Funtion Name:f_sort()

Argument: integer test[]

returnvalue string

------------------------------------------------------------------------------------------------*/

integer i,j,li_temp,li_sumnum

string ls_return

li_sumnum = upperbound(test[])

if li_sumnum = 0 then return ''

//进行li_sumnum-i趟排序

for i = 1 to li_sumnum 

//每趟要进行li_sumnum-i次比较

for j = i+1 to li_summun

if a[i]> a[j] then

li_temp = a[i]

a[i] =a[j]

a[j] =li_temp

end if

next

next

for i  = 1 to li_sumnum

if i = 1 then

ls_return = a[i]

else

ls_return = ls_return ','+a[i]

end if

next

return ls_return
