What is definition of file handling in c plus plus?
File is a place where information or data is stored. we make use of some of the file-handling functions in c like: fopen()-for opening a file. fclose()-to close a file. Every file being opened for any operations like: "r"- Read-Only mode. "w"-Write-only mode. "a"-append mode. "r+"-read+write mode. "w+"-write+read mode. "a+"-read+append mode. We should make use of FILE pointer ,in order to perform any such operations on the files. There are many input and output functions used along with files. fgetc() fgets() fscanf() fputc() fprintf() fputs() fseek() rewind() File handling is used to read or write a file without directly opening it.its contents are opened in another files by using above specified commands in c++ programming for file handling we have to use a header file but in c noheader file regarding to file handling is required
