A Study On File Input Output Operations & File Pointer Functions In C++. In real-time programming, we deal with large chunks of data that cannot be accommodated from standard Input-Output devices. Hence we need
This section describes some file input and output built-in functions. fopen() opens a file for reading and writing. fclose() closes an opened file. fread() reads data from input files. fwrite() writes data to output files.
