Regarding syntax of 'scanf' function.
In the program, we write, scanf("%[^\n]s", string_name).

I tried missing the [^\n] part, but the result is virtually the same. 
Please explain, what exactly is its use in spacing?

In C programming language, whenever scanf() function encounters space, it stops taking further more input for a particular variable.  ^ is the caret operator and it helps us to ignore a particular character. Thus, when we write "^\n" in scanf() function, we will be able to write strings with spaces (like hello world) and also be able to store in a particular variable, until \n (here, \n is Enter key) is encountered.
