Line breaks and Linux carriage returns in Windows

The example text of line feed carriage return and Linux carriage return in Windows is as follows: fsad6546F5343646546345asfdsafsadfsda456749 + 8ASDFSAD: read the first line of Windows

The example text of line feed carriage return and Linux carriage return in Windows is as follows: fsad6546F5343646546345asfdsafsadfsda456749 + 8ASDFSAD: read the first line of Windows

The example text of line breaks and Linux carriage returns in Windows is as follows:

Fsad6546
F5343
646546345 asfdsa
Fsadfsda
456749 + 8
ASDFSAD

Read the first line

In Windows, the first line ends with \ r \ n, and the eight characters are followed by '\ r \ n'. when reading the C language fgetc, the ninth and tenth characters are both '\ n', And the next line of F is 11th characters

In Linux, there is no carriage return '\ R' and there is a line break. After reading 8 characters, it is' \ n', And the next line of F is the tenth character.

The following program reads text files and then outputs

(Be sure to get the length of a row first)

Char d;
Int k = ftell (pfile );

If (fgets (str, I + 2, pfile) = NULL)

}

Printf (str );

}
Fclose (pfile );
Return 0;
