Non-binary files are known as text files, and some translations may occur due to formatting of some special characters (like newline and carriage return characters). If the function is called with any value in that parameter the default mode is overridden, not combined.ДЇile streams opened in binary mode perform input and output operations independently of any format considerations. Myfile.open ( 'example.bin', ios::out | ios::app | ios::binary) Д®ach of the open member functions of classes ofstream, ifstream and fstream has a default mode that is used if the file is opened without a second argument:ДЇor ifstream and ofstream classes, ios::in and ios::out are automatically and respectively assumed, even if a mode that does not include them is passed as second argument to the open member function (the flags are combined).ДЇor fstream, the default value is only applied if the function is called without specifying any value for the mode parameter. For example, if we want to open the file example.bin in binary mode to add data we could do it by the following call to member function open: If the file is opened for output operations and it already existed, its previous content is deleted and replaced by the new one.ДЄll these flags can be combined using the bitwise operator OR ( |). If this flag is not set, the initial position is the beginning of the file.ДЄll output operations are performed at the end of the file, appending the content to the current content of the file. Set the initial position at the end of the file. Where filename is a string representing the name of the file to be opened, and mode is an optional parameter with a combination of the following flags: In order to open a file with a stream object we use its member function open: An open file is represented within a program by a stream (i.e., an object of one of these classes in the previous example, this was myfile) and any input or output operation performed on this stream object will be applied to the physical file associated to it. This procedure is known as to open a file. The first operation generally performed on an object of one of these classes is to associate it to a real file.

This code creates a file called example.txt and inserts a sentence into it in the same way we are used to do with cout, but using the file stream myfile instead. For example, on an architecture (such as x86-32) where sizeof(int) = 4 and sizeof(int *) = 4, the expression sizeof(array) / sizeof(array) evaluates to 1, regardless of the length of the array passed, leaving the rest of the array unaffected.// basic file operations #include #include using namespace std

As a result, sizeof(array) is equal to sizeof(int *). However, array is a pointer type because it is a parameter. In the following example, the function clear() uses the idiom sizeof(array) / sizeof(array) to determine the number of elements in the array.

One of the problems with arrays is determining the number of elements. Number of characters prior to the null terminator. Figure 2.1 shows a string representation of вЂњhello.вЂќ The length of a string is the number of bytes preceding the null character, and the value of a string is the sequence of the values of the contained characters, in order. A pointer to a string points to its initial character. String Data TypeДЄ string consists of a contiguous sequence of characters terminated by and including the first null character. The standard C library supports strings of type char and wide strings of type wchar_t.

Strings are a fundamental concept in software engineering, but they are not a built-in type in C or C++. As a result, weaknesses in string representation, string management, and string manipulation have led to a broad range of software vulnerabilities and exploits.

Graphics- and Web-based applications, for example, make extensive use of text input fields, and because of standards like XML, data exchanged between programs is increasingly in string form as well. Strings from sources such as command-line arguments, environment variables, console input, text files, and network connections are of special concern in secure programming because they provide means for external input to influence the behavior and output of a program.
