How ?

scanf("%[^t]",para);

1. Here scanf will accept Characters entered with spaces.
2. It also accepts the Words , new line characters .
3. [^t]  represent that all characters are accepted except tab(t) , whenever t will encountered then the process of accepting characters will be terminated.

Drawbacks :

1. Paragraph Size cannot be estimated at Compile Time
2. It’s vulnerable to buffer overflows.
