Thread: Int to String Functions?

Are there any int to string conversion functions?

base? what do you mean?

itoa is non-standard.
Use a stringstream

In the new faq thread on the General Disucssions board,

Code:

#include <sstream> //this header automatically includes iostream and is needed for ostringstream
#include <string> 
using namespace std;

string IntToString(int num); //this will be our converter function

int main(void)
{     int number=5;
      string result=IntToString(number);
      cout<<result<<endl;
      cin.get();
      return 0;
}

string IntToString(int num)
{     ostringstream myStream; //creates an ostringstream object
      myStream<<num<<flush; 
      /*outputs the number into the string stream and then flushes
      the buffer (makes sure the output is put into the stream)*/
      return myStream.str(); //returns the string form of the stringstream object
}

Code:

template <typename T>
std::string ToString(const T& number)
{
    std::ostringstream os;
    os << number;
    return os.str();
}

True, but two things...

Is a beginner gonna know how to use templates?
Are they needed in this instance?

The answer to both is probably no.

Well, if the only thing being converted are int's, then no, templates aren't necessary at all, but still is good to know what your options are, don't you think?
One should aim at making code reusable, and this was just a very humble example.
