You can use the methods get() and put() to read or write single characters.
The get() method reads the next character from a stream and stores it in the given char variable.
char ch; cin.get(ch);
If the character is a white space character, such as a newline, it will still be stored in the ch variable.
To prevent this from happening you can use
cin >> ch;
to read the first non-white space character.
The get() method can be called without any arguments.
In this case, get() returns the character code of type int.
int c = cin.get();
The put() method can be used for unformatted output of a character.
The character to be output is passed to put() as an argument.
This statement is equivalent to cout << 'A'; , where the field width is undefined or has been set to 1.
