I am trying to declare a stringstream to use to reverse a number to see if it is a palindrome (input is an int passed into the function)- 

stringstream ssInput;
ssInput << input;
string reverseInput = ssInput.str();

I modeled it after this question -

Easiest way to convert int to string in C++

Why am I getting this error?

aggregate 'std::stringstream ssInput' has incomplete type and cannot be defined| ||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

Have you included 

#include <sstream>

? It should also be needed to add using namespace std or to use fully qualified name std::stringstream instead of simply stringstream.
