Answer 2

Predefined streams in C++:

• Predefined streams are those streams that are already embedded in the computer system by default. These streams get activated, when the program starts executing.

These are the multiple predefined streams that are available in C++ :

• cin: It is an input object, which takes it through standard input device like keyboard. It is similar to stdin in C. It uses extraction operator '>>' to read the data.
• cout: It is an output object, which gives output to standard output device like monitor. It is as similar to stdout in C and uses insertion operator '<<' to display the data.
• cerr: It is a standard error object, which is used to manage the errors in unbuffered type of data. This object is used to pass the errors that have occurred in unbuffered data to output device like monitor. Its functions are similar to stderr in C.

• clog: It is often a standard an error object, but it manages the errors that takes place in buffered type of data.
