boost::format, std::stringstream

stringstream完全适用， boost::format感觉代码可读性不好，可能还不习惯吧

#include <iostream>
#include <boost/format.hpp>
#include <string>
#include <sstream>

int _tmain(int argc, _TCHAR* argv[])
{
	std::string str = "sum";
	int i = 100, j = 200;
	std::cout << boost::format("%s:%d+%d=%d")%str%i%j%(i+j) << std::endl;
	
	boost::format fm("product:%1% * %2% = %3%");
	std::cout << fm %3 %5 %(3*5) << std::endl;

	int *p = &i;
	std::cout << boost::format("address:0x%x")%p << std::endl;

	std::stringstream ss;
	ss << str << ":" << i << "+" << j << "=" << i+j;
	std::cout << ss.str() << std::endl;

	system("pause");
	return 0;
}
