How does cin and cout work in C++?
‘c’ is a char type and you perform cin >> c; twice, which means it’ll read two char s when they’re available. So, it reads ‘a’ then prints it via cout << c; and then reads ‘b’ and prints it. Therefore, it is expected that ‘a’ and ‘b’ are printed (e.g., ab ).

What is the purpose of CIN?
The cin object in C++ is an object of class iostream. It is used to accept the input from the standard input device i.e. keyboard. It is associated with the standard C input stream stdin. The extraction operator(>>) is used along with the object cin for reading inputs.
What is cin and cout explain iostream?
std::cin is another predefined variable that is defined in the iostream library. Whereas std::cout prints data to the console using the insertion operator ( << ), std::cin (which stands for “character input”) reads input from keyboard using the extraction operator ( >> ).
