Capture the last record number using "awk" NR variable

Hi Team. I am trying to capture the last record number from a file using the below command ( assuming abc.txt has 21 records and I want 21 as output )
Code:
awk'{c=NR;print c}'abc.txt

But it is printing all the record number. Can someone please help modify the above command?
