Alternative to itoa() for converting integer to string C++?

I was wondering if there was an alternative to itoa() for converting an integer to a string because when I run it in visual Studio I get warnings, and when I try to build my program under Linux, I get a compilation error.

Solution

  • In C++11 you can use std::to_string:

    #include <string>

std::string s = std::to_string(5);

    If you're working with prior to C++11, you could use C++ streams:

    #include <sstream>

int i = 5;
std::string s;
std::stringstream out;
out << i;
s = out.str();
