Putting in a single if statement:
is_changed
if [ !-e $file -o $? == 0 ];then
print $file
fi
It assumes that your function is_changed returns 0 if it's changed and something else otherwise.

i have some file in my directory like
a.txt
a.txt.md5
b.txt
b.txt.md5
c.txt
and i am trying to write a shell script which will print the name of file of which Md5 is no present or Md5 is changed
like
for filename in ".txt"
do
if($filename.md5 not present OR $filename.md5 is changed)
echo $filename
fi
done
so how will this if condition be like?
if($filename.md5 not present OR $filename.md5 is changed)

Test if the file exists is easy:
if [ -e $file ]; then
#checksum again
if [ $? == 0 ];then
echo $file
fi
else
echo $file
fi
I am just abstracting whatever you do to check checksum
perhaps I better add a pseudo code:
if file exists
checksum
if changed
print filename
else
print filename
