Standard output, cout, is an object of the class ostream, as is cerr, the standard error output. Or you can have the library open an ostream for you (in which case the file is opened with ios::trunc ).

To get cout to accept a Date object after the insertion operator, overload the insertion operator to recognize an ostream object on the left and a Date on the right. The overloaded << operator function must then be declared as a friend of class Date so it can access the private data within a Date object.

The << is a binary operator whose first operand (left side) is an ostream and the second operand is an expression of simple types of a string. Grouping of the

pb_ostream_t stream = pb_ostream_from_buffer (buffer, sizeof (buffer)); Now we will set the values of the fields of the message. Recall from the.proto definition that we had a field called integer, which is an int, and a field called message, which is a string. For the integer field, we will assign it the value 10. This code displays a date using the cout object: C++. Date dt(1, 2, 92); cout < Ostream to string

This function overloads operator<< to behave as described in ostream::operator<< for c … Internally, the function accesses the output sequence by first constructing a sentry object. Then (if good), it inserts character into its associated stream buffer object as if calling its member functions sputc or sputn until n characters have been written or until an insertion fails (in this case it sets the badbit flag).

Basically, you are finding all permutations of the array using a recursive permutation algorithm. There are 4 things you need to change: First, start your loop from pos, not 0 Second, swap elements back after recursing (backtracking) Third, only test once you have generated each complete permutation (when pos = inline Flushes the stream contents to the target string and returns the string's reference.

Specific members are provided to perform these output operations (see functions below). The standard objects cout, cerr and clog are objects of this type. Add this to a static string utility class: public static Stream ToStream(this string str) { MemoryStream stream = new MemoryStream(); StreamWriter writer = new StreamWriter(stream); writer.Write(str); writer.Flush(); stream.Position = 0; return stream; } This adds an extension function so you can simply: The type ostream, which is the base class for any stream that accepts writes, such as ofstream and ostringstream. The standard stream objects: std::cout, std::cerr, std::clog and their 'wide' versions (e.g. std::wcout), are objects of this ostream class. The use of stringstreams to simplify string handling.

The overloaded << operator function must then be declared as a friend of class Date so it can access the private data within a Date object. It’s fairly easy to convert a C# String to a Stream and vice-versa. Convert String to Stream. To convert a C# String to a MemoryStream object, use the GetBytes Encoding method to create a byte array, then pass that to the MemoryStream constructor: from std::string to std::istream?.
