hello everyone
i have a large text file (about 5 GB) and with a program i should edit it with given information by user. when i use ordinary c++ functions related to files, it gives me error for that large file, however it works properly for a small text file.
how can i solve this problem? is there some special functions for large txt files?
Thanks & Regards
Jump to PostWhat exactly is the problem you have? Are you trying to read the whole file into memory at one time? Or just read small parts of it?

i should write 3 functions : search, insert, delete.
in search function user give me a number that is start of one line and i have to print that line for user.
in insert i have to write given data by user at the end of the file .
and in delet i have delet the line given it's number by user by put a special character at the end of it.
any reply??? :(
