Reading \r (carriage return) vs \n (newline) from console with getc?
c, console, getc, newline
Solution
`\n` is the newline character, while `\r` is the carriage return. They differ in what uses them. Windows uses `\r\n` to signify the enter key was pressed, while Linux and Unix use `\n` to signify that the enter key was pressed.
Thus, I'd always use `\n` because it's used by all; and `if (x == '\n')` is the proper way to test character equality.
Problem
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: ``` #include <stdio.h> int main() { int x = getc(stdin); if (x == '\n') { printf("carriage return"); printf("\n"); } else { printf("missed it"); printf("\n"); } } ``` The question I have, and what I tried at first was to do: `if (x == '\r')` but in testing, the program didn't catch me hitting enter. The `'\n'` seems to correspond to me hitting enter from the console. Can someone explain the difference? Also, to verify, writing it as `if... == "\n"` would mean the character string literal? i.e. the user would literally have to enter `"\n"` from the console, correct?
