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;}
