Problem with re-using a stringstream object

Question

I\'m trying to use safe practices in handling input with numbers only in C++, so I use a stringstream object as so:

#include 
#include 

        

Answer 1

A better way to do this conversion between datatypes would be to use boost::lexical_cast.

Info and examples can be found at the Boost Site.

Below is an example of doing an int to string conversion and back (string to int) such as what you're doing in your program.

#include 
#include 

int main(int argc, char *argv[])
{
    int i = 42;
    std::string s = boost::lexical_cast(i);
    int j = boost::lexical_cast(s);

    return 1;
}
