Integer to string in C++

Question

I have problem with converting integer to string in C++ using CodeBlocks and GCC Compiler. I tried with this but it eject error:

#include <iostream>
#include <string>

int main()
{
    int clicks = 0;
    string code = to_string(clicks); //error: "to_string" was not declared in this scope
}

And also i tried:

#include <iostream>
#include <string>

int main()

{
    int clicks = 0;
    std::string code = std::to_string(clicks); // error: "to_string" is not memeber of "std"

}

Is there any solution? Pls help

You have to compile with C++11 enabled (GCC flag: `-std=c++11`), but I don't know how you can set that in CodeBlocks. — Overv, Oct 13 '14 at 22:37
http://www.cplusplus.com/reference/cstdlib/itoa/ Not portable, but there are some portable alternatives that use `sprintf()` listed on that website. — Ricky Mutschlechner, Oct 13 '14 at 22:37
Check [`std::ostringstream`](http://en.cppreference.com/w/cpp/io/basic_ostringstream). — πάντα ῥεῖ, Oct 13 '14 at 22:37

You need to have support for C++11. How I figured that out? I checked the ref here and saw the C++11 icon.

See this answer on how to do this.

It pretty much says to follow these steps:

Go to Toolbar -> Settings -> Compiler
In the "Selected compiler" drop-down menu, make sure "GNU GCC Compiler" is selected
Below that, select the "compiler settings" tab and then the "compiler flags" tab underneath
In the list below, make sure the box for "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]" is checked
Click OK to save

You need to use stringstream like so:

stringstream ss;
ss << clicks;
std:string code = ss.str();

Include sstream.
