Empty string: Difference between revisions

=={{header|C}}==

In C the strings are <code>char</code> pointers. A string terminates with the null char (U+0000, <code>'\0'</code>), which is not considered part of the string. Thus an empty string is <code>"\0"</code>, while a null string is a null pointer which points to nothing.
