then figure out a way to make if find it more than once.

As a hint, use substrings in a loop, but for how to do that, you have to figure it out on your own. F10 helps. Good luck

werd... umm ok so this is what im thinking

code:

for i : 1..length(sentence)
c := index(sentence, find)
if c not= 0 then
count := count + 1
end if
end for

not quite - don't do a for loop, do a regular loop and use a counter for the begining of the substring, which you then set to the end of the searched for string - otherwise, you'll get it counting 3 "air" in "chair" ie chair +1 hair +1 air +1 ir +0 r +0 result ? 3 try again!

a hint : once you found a match, remove it so it doesnt get counted again. Continue on searching untill 0 matches found.

ok lets c here

code:

var s, t : string := ""
var count, i : int := 0
put "Enter sentence..."
get s
put "Enter words to find..."
get t
delay (2000)
cls
loop
i := index (s.t)
if i not= then
count := count + 1
s := s (i + 1 .. *)
end if
exit when i = 0
end loop
put count

w00t ?

It should be this.

code:

var s, t : string := ""
var count, i : int := 0
put "Enter sentence..."
get s
put "Enter words to find..."
get t
delay (2000)
cls
loop
i := index (s, t)
if i not= 0 then
count := count + 1
s := s (i + 1 .. *)
end if
exit when i = 0
end loop
put count

thats what i meant, as you can see there are a lot of errors, it was too early to think Razz

Actually in order to work even better to accept a full sentence it should be this

code:

var s, t : string
var count, i : int := 0
put "Enter sentence..."
get s:*
put "Enter words to find..."
get t:*
loop
i := index (s, t)
if i not= 0 then
count := count + 1
s := s (i + 1 .. *)
end if
exit when i = 0
end loop
put count

By the way, now that's we're on the topic of post counts, Is it just my imagination playing cruel tricks on me, or does my post count go down everytime I post in the spam section? Because I've know for a fact I've posted more than 89 times.

Posting in spam dose not make your count go down, it just dose not count posts in the spam section.
