How do I use grep to search the current directory for all files having the a string “hello” yet display only .h and .cc files?

grep -r --include=*.{cc,h} "hello" .

This reads: search recursively (in all sub directories also) for all .cc OR .h files that contain “hello” at this . (current) directory
