Hello there,
This may be a silly question, but is there any function to print a string with all the escape characters in it?
For example, instead of printing:
This is a string.
It would print:
This is a string.\n
Or in Windows:
This is a string.\r\n
I know that you can debug the code to find the variable contents, but is there any way to accomplish this with some standard library function?
Thanks in advance.

I'm not aware of any such standard library functions ... I think escape sequences are handled in the translation phase, which I believe happens somewhere in preprocessing.
You could write a function to handle this printing to the screen yourself based on the character value, but I'm guessing you already knew that.
Im not sure why you are asking for this, but if you only need to be able to see them, many text editors can display hidden characters.
A way of implementing this yourself would be to read in each character one by one from the file. When you come across an escape character, analyze it and print out the escape character as you want.
I was thinking about doing this on my own but I thought there was some standard library function to do that.
Thank you guys for the suggestions and for the help!
You have to roll your own.Originally Posted by koplersky
The function char *strtoescaped(char *str) shouldn't be hard to write. Just replace all the special characters with '/' plus the code, passing through for a first time to work out how much space to allocate.
