Reading \r (carriage return) vs \n (newline) from console with getc?

Question

I\'m writing a function that basically waits for the user to hit \"enter\" and then does something. What I\'ve found that works when testing is the below:

#incl         


        

Answer 1

The '\n' is the "Line Feed" and '\r' is the carriage return. Different operating systems will handle new lines in a different way, such as

Windows

Expects a newline to be combination of two characters, '\r\n'.

Linux\Unix and Modern Mac OS

Uses a single '\n' for a new line.

Classic Mac OS

Uses a single '\r' for a new line.

Basically, I would use if (x == '\n') as it is currently used by all modern operating systems.
