The input and output stream insertion operators read or write information from a file. In C++, the stream insertion operator << is used for output, while >> is used for input.Before we begin overloading these operators, we must first understand these points. cin and cout are objects of ...
with input streams. With input streams, theextraction operator (>>)is used to remove values from the stream. This makes sense: when the user presses a key on the keyboard, the key code is placed in an input stream. Your program then extracts the value from the stream so it can be ...

The right shift operator (>>) is overloaded to designate stream input and is called stream extraction operator. These operators used with the standard stream object (and with other user defined stream objects) is listed below:Operators Brief description cin Object of istream class, connected ...

The cin.get() method is a member function of the cin stream in C++. It is used to read a single character from the standard input (keyboard). Unlike the >> operator, which can leave whitespace characters in the input buffer, cin.get() reads the next character, including whitespace like...
Read a string from the stream usingoperator>> Try to convert the string to a double using one of various methods.std::stod,boost::lexical_cast, etc... If the test passes, set the double to infinity and return the stream, else:
A last point to mention is the performance aspect. Some informal benchmarks show that extracting withmandatory_inputis of roughly the same performance than extracting with uncontrolled placeholder characters. So this class is as consistent with stream extraction as one could dream. Surprisingly however...
