Why scanf function do not accept escape sequences as an input?

Hope that helps %s only reads in input up to the first whitespace character - in this case, the space. Thus, it only recognizes "hello", since the rest of the input has not been read.
That being said, scanf can't interpret escaped characters. You could put an actual newline in your input, but you can't use escaped characters and expect it to properly parse them.

Using scanf to accept user input

I hope this helps . Don't use scanf directly. It's surprisingly hard to use. It's better to read an entire line of input and to then parse it (possibly with sscanf).
Read this entry (and the entries it references) from the comp.lang.c FAQ: http://c-faq.com/stdio/scanfprobs.html

In programming, why are escape sequences for regex and escape sequences for string literals different?

fixed the issue. Will look into that further The escape sequences found in string literals are there to stop the programing language from getting confused. For example, in many languages a string literal is denoted as characters between quotes, like so
code :
my_string = 'x string'
my_string = 'x's string' # this will cause bugs
my_string = 'x\'s string' # lets the programing language know that the internal quote is literal and not the end of the string
regex_string = 'A.C'  # match an A, followed by any character, followed by C
regex_string = 'A\.C' # match an A, followed by a period, followed by C
regex_string = 'AsC'  # match an A, followed by s, followed by C
regex_string = 'A\sC'  # match an A, followed by a space character, followed by C

How do you input escape sequences in Python?

it helps some times The input statement takes the input that the user typed literally. The \-escaping convention is something that happens in Python string literals: it is not a universal convention that applies to data stored in variables. If it were, then you could never store in a string variable the two characters \ followed by n because they would be interpreted as ASCII 13.
You can do what you want this way:
code :
import ast
import shlex
a=input("Input: ")
print(ast.literal_eval(shlex.quote(a)))

C Redirection causes scanf to not accept input

it should still fix some issue It accepts input, it just accepts input from the file you've told it to accept input from.
You have three options with STDIN:

Label property to accept escape sequences in C#


By : shalini subramaniam

wish help you to fix your issue The Label control can't display the control characters encoded by escape sequences, and there's no property that controls that. The reason is it draws its text using standard graphics routines built into the framework, which do not expand control characters. Not to mention that the meaning of something like \t is ambiguous: how many spaces should be treated as a tab?
If you want to display something like a tab or skip to a new line, you'll need to hardcode it into your string:
