std::stringstream like a private variable in class

Question

I want to use std::stringstream like a private variable in my class. But i have an error "undeclared identifier". PLease, explain why and get me advice how can i do this.

class Test
{
private:
    std::stringstream str;    
}

*"But i have an error"* is as useful as "my cat could be on fire". Please always include the complete error report, including burning cats and line numbers — Zeta, Mar 30 '13 at 11:07

Most likely you haven't included the proper header file. Also, don't forget the semicolon at the end of the class definition:

#include <sstream> // <== This is what you need for std::stringstream

class Test
{
private:
    std::stringstream str;    
}; // <== Don't forget the semicolon
