How to extract a portion of a string in c++?

Question

I have a string as below:

string str="university";

and i want to take a portion if this str like "versi" and save it to another string how do i do that?

thanks.

This question appears to be off-topic because it is about completely trivial code that even day 1 programmers won't find useful. — user657267, Sep 05 '14 at 05:24
Why can't you read documentation before asking on forum. It would be faster! — Basile Starynkevitch, Sep 05 '14 at 05:26

Use substr() member function:

std::string portion = str.substr(start_index, size);

Read the online doc for better understanding. Read an introductory book on C++ as well.

Hope that helps.

Read carefully some documentation about std::string. You want to use the substr member function.
