C++ STL

Tnameh — Mon, 18 Sep 2006 04:07:54 GMT

I want to implement this in C++.I will have one file in which i will define Key and value.

What i want to do is that i wll read file once store all the value in
data structure. And wll do search for that particular key and it should
return me value of that particular Key. Key and Value are string and Key
will always be unique.

Can anyone suggest me better way of doing it Using C++,STL

For Example

file contents are

hello1:def
hello2:cef
Hello3:gef
Hello4:cef
Hello5:cef.

Suppose i search for hello2 it should return me cef.Hope i am clear.

I don't see Peter's example so I wrote my own. Most of the source is fluff to get the file and read it. The only important thing is the STL "insert": m_string[key] = value;
And the find: mss_iter itr = m_string.find(argv[2]);
