Good day,

I need help from you.

I have to split and create output files by every 30.000 recordings.
Example ,

Input file has 150.000 (transaction.txt) recordings of bank accounts transactions.
The C code has to split this file and create output files by 30.000 records each from input file.
(transaction1.txt, transaction2.txt, transaction3.txt and etc.).The transaction.txt (150.000 recordings) has to be split on many files with 30.000 recordings.
So , does anybody know how to do this?
How C code will look like for this operation?

Thank you very much.

first learn to open a file using fopen(), read a line from the input file using fgets() and write the same line to the output file using fprintf(). Once you can do that, come back and talk about how to actually split the file into two or more files.
