Whatever comes from the keyboard is stored in a buffer When you press enter the system passes the buffer to the application code (std::cin code) Depends on the type of the operand. Cin is an object of class istream that represents the standard input stream It corresponds to the cstdio stream stdin The operator >> overload for streams return a reference to the same stream
The stream itself can be evaluated in a boolean condition to true or false through a conversion operator Cin provides formatted stream extraction The operation cin >> x Where x is an int will. 3 there is no close equivalent to cin in c However, you can read things in c using the c standard library, you can look at the relevant part here (cstdio reference).
I am currently reading in with std::cin >> for the strings i expect to be single words and getline(std::cin, string) for the strings with spaces I am not getting the right output, though. cin, cout, system не являются однозначными, как убрать ошибки? Вопрос задан 6 лет назад Изменён 4 года 11 месяцев назад Просмотрен 74k раз When using std::getline(std::cin, s) i would get a very messy and i would say, interrupted input when waiting for inputs in a while / for loop This option resolved my issue! Using cin's >> operator will drop leading whitespace and stop input at the first trailing whitespace
To grab an entire line of input, including spaces, try cin.getline(). How do i use cin for an array asked 7 years, 2 months ago modified 1 year, 9 months ago viewed 78k times Even if @david g has answered the question on how it works, i wanted to add a way on how to read a boolean using std::cin which might be useful for others to understand and use.
