What is file mode in c plus plus?
There are 6 main types of file opening mode:* "r". Open file for reading and file must exist; * "w" Open file for writing. If file does not exist it is created or if life already exist it's content is erased. * "a" Open file for appending. It adds all information at the end of the file leaving old data untouched. If file does not exist it is created. * "r+" Open file for reading and writing and file must exist. * "w+" Open file for writing and reading. If file does not exist it is created or if life already exist it's content is erased. * "a+" Open file for appending and reading. Again all new data is written at the end of the file old data leaving untouched. If file does not exist it is created. (You can read old data by moving pointer in file using fseek or rewind functions from stdio.h. But all writing operations will be done at the end of the file no matter how you change pointer) It is assumed by default that file will be standard ASCII text file in order to open file as binary file, you need to add "b" indicator:FILE *myFile = fopen("myfile.txt", "wb");/ * following two has identical meaning */FILE *myFile = fopen("myfile.txt", "w+b");FILE *myFile = fopen("myfile.txt", "wb+");
What is file mode and list various file mode operations available?
A file mode describes how a file is to be used, to read, to write to append etc. When you associate a stream with a file, either by initializing a file stream object with a file name or by using open() method, you can provide a second argument specifying the file mode. e.g. stream_object.open("filename",filemode); Following is the list of filemodes available in C++ ios::in ios::out ios::binary ios::ate ios::app ios::trunc ios::nocreate ios::noreplace

What is the difference between binary file and text file in java?
HI... When you access a file from within C or C++ you have a choice between treating the file as a binary file or as a text file. C uses the fopen(file,mode) statement to open a file and the mode identifies whether you are opening the file to read, write, or append and also whether the file is to be opened in binary or text mode. C++ opens a file by linking it to a stream so you don't specify whether the file is to be opened in binary or text mode on the open statement. Instead the method that you use to read and/or write to the file determines which mode you are using. If you use the operator to write to the file then the file will be accessed in text mode. If instead you use the put() and get() or read()and write() functions then the file will be accessed in binary mode. So what exactly is the difference between text and binary modes? Well the difference is that text files contain lines (or records) of text and each of these has an end-of-line marker automatically appended to the end of it whenever you indicate that you have reached the end of a line. There is an end of line at the end of the text written with the C fwrite() function or in C++ when you

Can you open a file in read only mode?
All major operating systems allow developers to write code that can open a file in a variety of different ways, including "r" or "ro" (read-only) "rw" (read-write), "w" (write-only), and "a" (append, like "w" but starts at the end of the file, preserving the previous contents). In these operating systems, applications may choose to open a file as "read-only", which prevents accidental modification of the file by logic errors in the code.
