23 | What is the difference between '\n' and '\r\n'? |
24 | ----------------------------------------------- |
25 | |
26 | There are a few characters which can indicate a new line. The usual ones are these two: |
27 | |
28 | * '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF). |
29 | * '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR). |
30 | |
31 | Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones: |
32 | |
33 | * DOS and Windows |
34 | They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10). |
35 | |
36 | * Unix (and hence Linux as well) |
37 | Unix uses a single '\n' to indicate a new line. |
38 | |
39 | * Mac |
40 | Macs use a single '\r'. |
41 | |
42 | To unify things a bit, so that writing portable C/C++ programs is possible, file streams have both a |
43 | "translated" and an "untranslated" mode. If you open a file in translated mode, the runtime library |
44 | will convert a '\n' to the appropriate newline character(s). If the following program is compiled under |
45 | Unix, the file will contain a single LF to indicate the newline. If it's compiled under windows, it will |
46 | contain a CRLF. |
47 | |
48 | #include <stdio.h> |
49 | #include <stdlib.h> |
50 | int main() { |
51 | FILE *fp = fopen("testfile.txt", "w"); |
52 | fprintf(fp, "Hello World\n"); |
53 | fclose(fp); |
54 | return 0; |
55 | } |
56 | |
57 | Important |
58 | If you want to be able to read text files written on different operating systems, you have to open the file |
59 | in binary (= untranslated) mode and check for the different newlines yourself. |
