Insert Carriage Return in unformatted text file

Question

C++ problem. I have a text file with no "carriage return" or "new line".

All the words are concatenate in a whole single block.

I want to divide the file in lines by substituting every substring "ABC" with the "carriage return" or "new line" character.

P.S: I can't scan the file line by line because the file is actually a single line, bigger than the max value allowed for a single string (string::max_size).

You can't operate on the file directly. You read from a backup version, parse for `"ABC"` and output other text or `'\n'` alike. — πάντα ῥεῖ, Apr 03 '15 at 09:20
I can change the string "ABC" with another string in the code program. — user3133076, Apr 03 '15 at 09:50

I solved with the following code:

ifstream  input("File_In");
ofstream output("File_Out");

for (unsigned long long int SEEK=0 ; SEEK<(MAX_LIMIT) ; SEEK++)
{
input.seekg(SEEK);
char tmp[4] ;
input.read(tmp,3);
output<<tmp[0];
if (string(tmp)=="ABC") output<<'\n';
};
