scanf("%[^\t]s", para); |
- Here scanf will accept Characters entered with spaces.
- It also accepts the Words , new line characters .
- %[^\t]s represent that all characters are accepted except tab(t) , whenever t will encountered then the process of accepting characters will be terminated.
Drawbacks :
- Paragraph Size cannot be estimated at Compile Time
- It’s vulnerable to buffer overflows.
