To perform I/O operations on file, we must use _____________ header file.

A file processing application must read a large text file from disk, perform some operations on the data, and write the results to another file. The application aims to optimize the I/O operations for efficient processing.Which of the following options is a suitable approach to handle this scenario?Answer( Please choose a correct answer )   CLEARUse a buffered reader and writer to read and write the file in chunks, reducing I/O overhead.Employ a compression algorithm to reduce the file size before performing I/O operations.Enable file system caching to improve read/write performance for the input file.Implement a multi-threaded approach to parallelize file reading and writing for faster processing.

Which of the following operations can be performed on the file "NOTES.TXT" using the below code?FILE *fp;fp = fopen("NOTES.TXT", "r+");ans.
