Can we use two variables in single line by putting comma and assigning them values?

Answer 1

Yes, this should work fine.
int a = 10, b = 20;

Answer 2

Actually I tried but it does not work.Thanks for replying.

Answer 3

Yes. But both variable should be same data type.
int a=10,b=20;

If you're using different data type separate them by semicolon " ; "
int a=10 ; float b=20.5;

Are you clear now?
