Getting the ASCII value of escape sequence character from 2 chars [on hold]

I'm reading chars from a file and whenever I read a char with value of 092 that is '' I want to read this char and the next char as one and get their ascii value, is that possible?
e.g. if I read '' and the next char is 'n' I want to be able to get the value 010.
I'm getting chars in while using a while cycle and char c = fgetc(source).

of course that's possible. By storing the fact that you encountered and a switch/case on the next char read.

Yes, it is possible. Many ways to do it. You should try something first, snd then askfor help with that, when you run into an actual problem. One way to go about this would be to have variable for current and previous char, and play with them. Another could be to just have a bool flag telling if previous char was your escape char . Or something else.

Give it a try and if you don't get it working, then show your code, what you have tried and what does not (yet) work correctly. (Minimal, Complete, and Verifiable example)

In C,92is not the character back-slash (ASCII 92).digitbegins an octal-escape-sequence, not decimal. You need to post the code you have used - next time, rather than only describe the problem.

n is used in some programming languages and some types of configuration files and some types of documents (e.g. JSON). Are you writing a lexer? Surely there is one already for whatever type of file you are reading. You also need a complete list of the escapes you want to support.
