How Many Times?

[Arpan]

Consider the following sentence:

Peter and I play together and also go to the same school and both of us
are in class V.

How do I find out how many times the string "and" has appeared in the
above sentence?

Thanks,

Arpan

Will this help? Watch for word-wrap.

Option Explicit

Const cAND = " and "
Const cLIN = "Peter and I play together and also go to the same school and
both of us are in class V."

MsgBox and1(cLIN),vbInformation,"1"
MsgBox and2(cLIN),vbInformation,"2"

Function and1(s)
Dim i, j
i = 0
Do
and1 = i
j = InStr(s,cAND)
If j = 0 Then Exit Do
s = Mid(s,j+Len(cAND)+1)
i = i + 1
Loop
End Function

Function and2(s)
Dim i, m, r, x
Set r = New RegExp
r.Pattern = cAND
r.IgnoreCase = False
r.Global = True
Set m = r.Execute(s)
For Each x in m
i = i + 1
Next
and2 = i
End Function

A revised version:


Option Explicit

Const cP = " and "
Const cS = "Peter and I play together and also go to the same school and
both of us are in class V."

MsgBox one(cS,cP),vbInformation,"one()"
MsgBox two(cS,cP),vbInformation,"two()"

Function one(s,p)
Dim i, j
i = 0
Do
one = i
j = InStr(s,p)
If j = 0 Then Exit Do
s = Mid(s,j+Len(p)+1)
i = i + 1
Loop
End Function

Function two(s,p)
Dim i, m, r, x
i = 0
Set r = New RegExp
r.Pattern = p
r.IgnoreCase = False
r.Global = True
Set m = r.Execute(s)
For Each x in m
i = i + 1
Next
two = i
End Function

<script runat='server' language='Jscript'>

s='Peter and I play together and also go to the same school'
s+='and both of us are in class V.'

alert(s)

a = s.match(/\band\b/g)

response.write(a.length)



</script>

s='Peter and I play together and also go to the same school'

must add a space here:

s='Peter and I play together and also go to the same school '

s+='and both of us are in class V.'

alert(s)

a = s.match(/\band\b/g)

response.write(a.length)

without the added space the answer is 2
wth the space 3.

</script>

Jscript and vbscript are equal languages on the ASP platform.
