Compare two files and print the two lines with difference
I have two files like this:
#FILE 1
ABCD 4322 26485
JMTJ 5311 97248
XMPJ 4321 58978
#FILE 2
ABCD 4321 26485
JMTJ 5311 97248
XMPJ 4321 68978
What to do: Compare the two files and find those lines that doesn't match. And have a new file like this:
#FILE 3
"from file 1"
ABCD 4322 26485
XMPJ 4321 58978
"from file 2"
ABCD 4321 26485
XMPJ 4321 68978
many thanks!

imaxdiv
DIV(3) BSD Library Functions Manual DIV(3)
NAME
div, ldiv, lldiv, imaxdiv -- quotient and remainder from division
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
div_t
div(int num, int denom);
ldiv_t
ldiv(long int num, long int denom);
lldiv_t
lldiv(long long int num, long long int denom);
#include <inttypes.h>
imaxdiv_t
imaxdiv(intmax_t num, intmax_t denom);
DESCRIPTION
These functions compute the value of num / denom and return the quotient and remainder in a specific divison structure. The functions differ
only with respect to the type of the return value and the parameters.
The returned structure always contains two members named quot and rem, denoting the quotient and the remainder. The type of these correspond
with the underlying type of the function.
EXAMPLES
The following example demonstrate the basic usage of the functions.
div_t d;
int a = 4321;
int b = 1234;
d = div(a, b);
(void)printf("%d %d
", d.quot, d.rem);
SEE ALSO

STANDARDS
All described functions conform to ISO/IEC 9899:1999 (``ISO C99'').
