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).
The problem is that cin >> y is only storing the first word of the line the user types, the asker wants to know how to store the entire line in y, such that file << y writes the full line to the file.
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?

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().
