C input output stream
WebC stdlib is the standard C library for input-output operations. Two essential streams play their role when dealing with input-output operations in C. These are: Standard Input (stdin) Standard Output (stdout) Standard input or stdin is used for taking input from devices such as the keyboard as a data stream. WebOutput stream objects can write sequences of characters and represent other kinds of data. Specific members are provided to perform these output operations (see functions below). The standard objects cout, cerr and clog are objects of this type. This is an instantiation of basic_ostream with the following template parameters:
