Escape character in C

Question

So I want to check if someone enters: \\n (\'\\\' and then \'n\') from the keyboard to a string, so I\'m doing something like this:

Answer 1

if user enter like \ and n using keyboard .

then try like this

 if(str[i] == '\\' && str[i+1] == 'n')

As \ is represented by \\, so use \\ instead of \ to check.
