Whatever comes from the keyboard is stored in a buffer You're using the extraction operator, so when cin is sending values to your variables, it skips leading whitespace in the buffer and stops on the next whitespace When you press enter the system passes the buffer to the application code (std::cin code)

Depends on the type of the operand.
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). 79 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. 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!
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. 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(). cin, cout, system не являются однозначными, как убрать ошибки?

How do i use cin for an array asked 7 years, 1 month ago modified 1 year, 8 months ago viewed 78k times I was taught that you have to use gets(str) to input a string and not cin However i can use cin just fine in the program below Can someone tell me if you can use cin or not
Sorry for my bad engl.
13 if the input stream isn't empty when you call cin, then cin uses the data already in the buffer instead of waiting for more from the user
