Newbie strings question

I was wondering how you could combine fixed strings and variables into one variable.

You can just string streams to do such a task. Note that this might not work with ancient compilers, but it's standard as of 97.

Code:

#include <sstream>
#include <string>
#include <iostream>
#include <cmath>

int main() {
	float pi = 3.14159265;
	double e = exp(1);
	int twentyThree = 23;
	char charArray[] = "deprecated";
	char theLetterB = 'b';

	std::ostringstream outStream;

	outStream << pi << " " << e << " " << twentyThree << " " << charArray << " " << theLetterB <<
	 " more stuff\n";

	std::string allOfEmCombined = outStream.str();

	std::cout << allOfEmCombined;

	return 0;
}

thanks
