What does this section of visual basic code do?

Question

For intSub=1 to 4
For intInnerSub=1 to 4
intSubNext = intInnerSub + 1
If (strFirstName(intInnerSub) > str First name(intSubNext) then
strSwap = strFirstName(intInnerSub)
strFirstName(intInnerSub) = strFirstName (intSubNext)
strFirstName(intSubNext) = strSwap
End If
Next intInnerSub
Next intSub

What does this code mean as a whole and what does each line of code perform? I cannot figure this out. By the way strFirstName is an array with five elements.

Thank you so much

Answer 1

it arranges the elements in strFirstName in ascending order (alphabetically, assuming they r strings) in each iteration, it compares each element with the element after it, and swaps them when necessary...

this sort of programs depends on a method called 'bubble sorting'...if u still cant figure it out... i suggest u try this link:
