How does the %(modulus) operator in c works?

Question

I was trying the following code

printf("%d", 010 % 10);

I was expecting it output be 0, but it is 8.

Why? Is there any way to get the last digit of an integer which is taken as input.

All integer literals starting with`0` are octal (including, a little known fact, zero itself). — paxdiablo, Jul 08 '19 at 12:24

Any numeric literal in c or c++ starting with a zero will be interpreted as octal

So your calculation is 8 modulo 10, which is 8
