1) cin.ignore 2) cin.clear ? Simply: 1) To ignore (extract and discard) values that we don't want on the stream 2) To clear the internal state of stream. After using cin.clear internal state is set …

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().

Otherwise, use std::string instead of char[]. cin >> name reads only the first whitespace-delimited word, leaving any remaining data in the input buffer, including the ENTER key, which is then …

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.

More correctly, cin reads from "standard input" (stdin). This may be the console, but it could also be a file or other device depending on the operator system and redirection by the user.

So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth. Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as …

If you use "cin >> noskipws >> str" and the user enters "a b c", str will contain "a" and the rest of the input will be lost. getline () must be used if you want to read the whole text with whitespace.

Other answers would have you disallow a particular number, or tell the user to enter something non-numeric in order to terminate input. Perhaps a better solution is to use std::getline() to …

I'm looking for a (multiplatform) way to do non-blocking console input for my C++ program, so I can handle user commands while the program continually runs. The program will also be …
