Print results at conclusion of bash 'for loop' - bash

Question

I'm a beginner.
I have a Bash script that embeds subtitles into mkv files if they exist in a directory.
for i in *.mkv; do
if [ -f "${i%mkv}"*"srt" ]; then
ffmpeg -i "$i" -f srt -i "${i%mkv}"*"srt" -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s srt $i.output.mkv
mv "${i%mkv}"*"srt" "${i%mkv}srt".old
mv $i $i.old
mv $i.output.mkv $i
else
echo $i "does not have srt file"
fi
done
It looks for all .mkv files that have an associated .srt file and does some ffmpeg magic to it. If it does not find an associated .srt file it says that the .mkv file "does not have srt file."
How can I make it so that at the conclusion of the for loop I get a print out of all the .mkv files that did have an .srt file and did successfully do all the other actions?
Thank you.

Let's use a Bash array to store completed or skipped MKVs:
SUCCESSMKVS=()
SKIPMKVS=()
for i in *.mkv; do
if [ -f "${i%mkv}"*"srt" ]; then
ffmpeg -i "$i" -f srt -i "${i%mkv}"*"srt" -map 0:0 -map 0:1 \
-map 1:0 -c:v copy -c:a copy -c:s srt "${i}.output.mkv"
mv "${i%mkv}"*"srt" "${i%mkv}srt".old
mv "$i" "${i}.old"
mv "${i}.output.mkv" "$i"
SUCCESSMKVS+=("$i")
else
echo $i "does not have srt file"
SKIPMKVS+=("$i")
fi
done
echo "The following MKVs succeeded:"
for mkv in "${SUCCESSMKVS[#]}"; do
echo -e "\t${mkv}"
done
echo
echo "The following MKVs were skipped:"
for mkv in "${SKIPMKVS[#]}"; do
echo -e "\t${mkv}"
done
echo
