how do you type cast int to string?

[LB]

You don't.

Perhaps you want to convert an integer to a std::string? If so, use std::stringstream as shown here:

Use std::stringstream :

#include <sstream>
#include <iostream>

int main() {
  int x = 10;
  std::stringstream y;
  y << x;
  std::cout << y.str() << std::endl;

  return 0;
}

#include <iostream>
#include <string>

int main() 
{
	int x = 10;
	std::string s = std::to_string(x);
	std::cout << s << std::endl;
}

when I use stringstream I get a weird error and my compiler doesnt recognize to_string(). For stringstream the error is "implicit instantiation of undefined template 'std::stringstream<char........"

and ftw I triend streamstream before using that exact article found on google and got this error.

[Peter87]

did you #include <sstream> ?

Until c++11 is the dominant standard, it would be cool if people tagged c++11 specific code!
