C scanf() question (no. 2) [SOLVED]

Question

Consider this code:

Why is the newline character still there after giving a 2-line input? Shouldn't it be consumed by "%*c" ?

Answer 1

I don't think you need the 's' after the set. It will try to match a corresponding 's' in the input stream, instead of belonging to the set, and therefore cause scanf() to abort early when encountered:

Answer 2

Calvin,
Shadow is right, so instead of

scanf("%[^\n]s %*c %s", a, b);

You can try

scanf("%[^\n]%*c %s", a, b);

Tried it, and seems to be working fine

Answer 3

Do you give name inputs on single line or in separate line?

Answer 4

Ipang It's separate.

Answer 5

Shadow and Ipang Thanks a lot! That makes sense; I had thought that the inclusion-exclusion set required an 's'.
