C++ Working With Files 
So far, we have learned about the iostream standard library, which provides cin and cout methods for reading from standard input and writing to standard output, respectively. In this tutorial, you will learn how files are handled in C++ programs and what are functions and syntax used to handle them.
The data is stored in the secondary device using the concept of files. Files are a collection of related data stored in a particular storage device
Working with files generally requires the following kinds of data communication methodologies:. – Data transfer between the program and the disk file.

Which of the following statements opens the file info.txt for both input and output? a. The marker is the character that marks the end of a file, and is automatically written when the file is closed
This state bit can be tested to see if the end of an input stream is encountered. This member function reads a single character from a file
12.To access files from a C++ program, you must use this directive: a. To set up a file to perform file I/O, you must declare: a
[Solved] Outside of a C++ program, a file is identified by… 
Outside of a C++ program, a file is identified by its ________while inside a C++ program, a file is identified by a(n) ________.. Which of the following is the member function that writes a single character to a file?
To write to a file, you use the file_write function.. Which of the following statements opens a file and links it to a file stream object?
When passing a file stream object to a function, you should always pass it by reference.. When data is read from a file, it is automatically stored in a variable.

O: Opening, Reading, Writing and Closing a file 
A file is a container in computer storage devices used for storing data.. – When a program is terminated, the entire data is lost
– If you have to enter a large number of data, it will take a lot of time to enter them all.. However, if you have a file containing all the data, you can easily access the contents of the file using a few commands in C.
When dealing with files, there are two types of files you should know about:. You can easily create text files using any simple text editors such as Notepad.
C++ File Handling 
As you know, standard input and output operations are performed by using streams in C++.. So far, you have been using the iostream standard library, which provides cin and cout methods for reading from standard input and writing to standard output respectively.
C++ provides stream called fstream to perform read and write operations on files.. C++ provides the following classes to perform operations on files:
– Create an stream object (input or output or I/O) by declaring the stream to be appropriate class.. – Associate a file stream object that is open the file by using constructor or by using open() function.
End of File Function –C++ 
exact contents of a file may not be precisely known.. Usually the general format style of the file and the type of data
data? Of course, we let the computer do the counting.. ), that returns nonzero (meaning TRUE) when there are
know the exact number of data items in the file, which we do not know.. file contains an undermined number of integer values
File Handling in C++ | How to Open, Read and Close 
File handling in C++ is a mechanism to store the output of a program in a file and help perform various operations on it. Files help store these data permanently on a storage device.
It helps to describe, diagnose, predict or prescribe. But to achieve all this, we need to store it somewhere
You are right! But here we are discussing at a level of programming. In contrast, text editors like ‘Notepad’ and ‘MS Office’ are pre-built and cannot be accessed at the programming level to store data
IBM Documentation 
FILE *fopen(const char *filename, const char *mode);. The fopen() function opens the file that is specified by filename
The mode variable contains one positional parameter followed by optional keyword parameters.. The possible values for the positional parameters are:
Each line ends with a new-line character, except possibly the last line, depending on the compiler. The system can insert or convert control characters in an output text stream
C++ Files And Streams 
Whether it is the programming world or not, files are vital as they store data. This article discuss working of file handling in C++
File handling provides a mechanism to store the output of a program in a file and to perform various operations on it.. A stream is an abstraction that represents a device on which operations of input and output are performed
These classes are derived from fstrembase and from the corresponding iostream class. These classes, designed to manage the disk files, are declared in fstream and therefore we must include fstream and therefore we must include this file in any program that uses files.
File Input/Output 
In order to read information from a file, or to write information to a file, your program must take the following actions. 2) Open the file and store this “file” with the file variable
Two, we read one value (or a single line of values) at a time, whereas by default in Matlab, you may read many values at once.. The basic steps for using a File in C are always the same:
Check to make sure the file was successfully opened by checking to see if the variable == NULL. Use the fprintf or fscanf functions to write/read from the file
PHP File Open/Read/Close 
In this chapter we will teach you how to open, read, and close a file on the server.. We will use the text file, “webdictionary.txt”, during the lessons:
second parameter specifies in which mode the file should be opened. also generates a message if the fopen() function is unable to open the specified file:
The file may be opened in one of the following modes:. Erases the contents of the file or creates a new file if it doesn’t exist
