Cast int to string

[navig8tr]

While trying to figure out how to cast an int to a string I came across this code:

#include <iostream>
#include <string>
 
int main() 
{
    double f = 23.43;
    std::string f_str = std::to_string(f);
    std::cout << f_str << '\n';
}

Unfortunately, using Dev C++ Version 5.4.2, I'm getting an error:

[Error] 'to_string is not a member of 'std'

Any ideas how to fix this?

Thanks in advance.

1. You don't have any ints here.
2. You don't need to cast it to a string if you are just using std::cout
3. std::to_string is C++11, Many compilers still don't support it. DevC++ probably never will.

here are some solutions:

#include <iostream>

int main()
{
    int i = 43;
    std::cout << i;
}

#include <iostream>
#include <sstream>

int main()
{
    int i = 43;
    std::stringstream ss;
    ss << i;

    std::string str;
    ss >> str;

    std::cout << str;
}

Whoops! That was a copy and paste from site where I found the code--I forgot to change the double to int.

Anyway, thanks for the alternate method.
