I saw this declaration:<br />
<br />
typedef map&lt;string,string&gt; line;<br />
<br />
<br />
as I understand it, it declares something like hashtable (value + key), so in declaration first &quot;string&quot; represents key or value?

I saw this declaration:

typedef map<string,string> line;


as I understand it, it declares something like hashtable (value + key), so in declaration first "string" represents key or value?

No, there is an non-standard hash_map&lt;&gt; collection class in some STL implementations.<br />
Map usually have some internal implementation of tree (binary, balanced, etc....) but there is no a rule about this. Anyway, this is transparent to the user.<br />

No, there is an non-standard hash_map<> collection class in some STL implementations.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
