Can you help with building a C$++$ program for file comparison. That can be efficient and work with large files.

requirements:

$1.$ the program should open two files that can ignore line breaks

$2.$ the program should run through the files and identify difrences or if same

$3.$ the program should print out the line and column for location purposes

$4.$ the program should give error if one file is longer or shorter than the other file

$5.$ the program should countinue running to countinue looking for diffrences if it encounters one

$6.$ the program should print where the issue has appeared in the text

$7.$ the program can countinue checking after the diffrence line of characters is presented unless there is a better way$`$

Example file $1($Is much more complex$)$:

abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$abc$123$

Example file $2($Is much more complex$)$:

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

abc$123$

Wanted output of program or something close to this:

if same:

file$1.$txt and file$2.$txt are identical.

$-------------------------------------------------------$

if diffrent:

file$1.$txt and file$2.$txt are diffrent.

Occurance $1$:

file$1.$txt has an occurance at line: # column: #

Diffrence present in:

$****************************************$

$^$

file$2.$txt has an occurance at line: # column: #

Diffrence present in:

$****************************************$

$^$

$-------------------------------------------------------$

if diffrent:

file$1.$txt and file$2.$txt are diffrent.

Occurance $2$:

file$1.$txt has an occurance at line: # column: #

Diffrence present in:

$****************************************$

$^$

file$2.$txt has an occurance at line: # column: #

Diffrence present in:

$****************************************$

$^$

$-------------------------------------------------------$

etc.
