C-Strings

C-String Variables l l Each character occupies 1 byte of memory. An important aspect of C-strings is that they must terminate with a byte containing 0. This is often represented by the character constant ‘’, which is a character with an ASCII value of 0. This terminating zero is called the null character. When the << operator displays the string, it displays characters until it encounters the null character.

String Constants

Reading Embedded Blanks l l It turns out that the extraction operator >> considers a space to be a terminating character. Thus it will read strings consisting of a single word, but anything typed after a space is thrown away.

Reading Embedded Blanks l l To read text containing blanks we use another function, cin. get(). This syntax means a member function get() of the stream class of which cin is an object.
