<DIV></DIV>&gt; 
<DIV></DIV>&gt;string.h is the C header file. ANSI C++ header files are without .h and 
<DIV></DIV>&gt;more properly written: 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;#include <IOSTREAM>
<DIV></DIV>&gt;#include <IOMANIP>// For setw() 
<DIV></DIV>&gt;#include <FSTREAM>// For file I/O 
<DIV></DIV>&gt;#include <STRING>
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;int main() 
<DIV></DIV>&gt;{ 
<DIV></DIV>&gt; using namespace std; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; string s1; 
<DIV></DIV>&gt; char pause; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; cin &gt;&gt; s1; 
<DIV></DIV>&gt; cout &lt;&lt; endl &lt;&lt; s1 &lt;&lt; endl; 
<DIV></DIV>&gt; cout &lt;&lt; "pause"; 
<DIV></DIV>&gt; cin &gt;&gt; pause; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;} 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;return 0; is not needed in ANSI C++. If in main() you do not return any 
<DIV></DIV>&gt;value, 0 is automatically returned to the system.

<DIV></DIV>&gt; 
<DIV></DIV>&gt;Hello, 
<DIV></DIV>&gt;A seemingly simple problem has stumped me so far. I cannot figure out 
<DIV></DIV>&gt;how to use simple strings in my programs. Do I need to add the 
<DIV></DIV>&gt;<CSTRING.H> library? If so, my compiler says it can't find it- can I 
<DIV></DIV>&gt;download this somewhere? I know I can get around this problem by using 
<DIV></DIV>&gt;an array of chars, but I want to be able to use strings. I am using Dev 
<DIV></DIV>&gt;4.01 and the mingw compiler 2.95.2-1. A thousand thanks for any help. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;D 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;When I try to compile this program, I can a 'string' undeclared (first 
<DIV></DIV>&gt;use this function) error. 
<DIV></DIV>&gt;// start 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;#include <IOSTREAM.H>
<DIV></DIV>&gt;#include <IOMANIP.H>// For setw() 
<DIV></DIV>&gt;#include <FSTREAM.H>// For file I/O

Positive. ANSI C++ header files have no .h and all their contents are
defined and declared in std namespace.

they spoke about it in my course they said iostream.h
