Solution: A locale is a set of features that are culture-specific, which can be used by programs to be more portable internationally.

Solution: A locale object contains information about which facet objects constitute a locale, and is each one of these facet objects that implements specific features as member functions.

Solution: There are 6 categories of facet in c++. They are collate, ctype, monetary, numeric, time and messages.

Solution: Every program has a single locale object which is its global locale.

Solution: Monetary facet will handle formatting and parsing of monetary values.

Solution: Input and Output operations of c can be performed in C++ using the C Standard Input and Output Library.

Solution: C++ library uses streams to operate with physical devices such as Keyboards, Printers, Terminals or with any other type of files supported by the system.

Solution: There are streams that are automatically created when executing a program. They are stdin, stdout and stderr.

Solution: There are three indicators are available in C++. They are Error indicator, End-Of-File indicator and Position indicator.

Solution: C++ input and output are type safety that means we don’t need to specify the type of variable we are printing.
eg:
in C we need to specify %d showing that an integer will be printed, whereas in C++ we just cout the variable.
printf(“%d”, a);
cout<
