When is your homework due, please, and should we expect to see _all_ of
your assignments?  If so, please post them in a batch for the
convenience of the people who feel like doing your work for you.

Are you really sure you actually count 3 occurences
of 'siva' in line 3 ?

Anyway, if you want to try this, it'd help you a bit in
reading a few pages as to explain to your trainor how
you made it up :

$ awk 'NF{print NF-1}' FS='siva' yourinputfile

This, on a little bit extended test file gives :

$ cat MISCFILES/countwordsinline.txt
123siva456siva789siva
222siva555siva
888siva 999siva
siva
888siva 999siva111visa
888siva 999siva111visa333

$ gawk 'NF{print NF-1}' FS='siva' MISCFILES/countwordsinline.txt
3
2
2
1
2
2

The exercise of printing out a 0 when necessary is left as
a bait for reading some pages ;-)

awk '{ l = $0
r = gsub("siva","")
printf "line %d: %d occurrences\n", NR, r
}'
