推荐答案
这个简单的方法怎么样 -
std :: ofstream out1（" xxx.log"）;
.. ..
std :: cout<< 记录和打印的东西;
out1<< 记录和打印的东西;
您也可以使用Macro技巧来完成这项工作，例如 -
#define PRINT （xxx）std :: cout<< 记录和打印的东西; \
out1<< 记录和打印的东西;
int main（）
{
//...
PRINT（要打印的东西）;
}

How about this simple way -
std::ofstream out1("xxx.log");
....
std::cout << "Something to log and print";
out1 << "Something to log and print";
You could also use Macro trick to get this done, something like -
#define PRINT(xxx) std::cout << "Something to log and print"; \
out1 << "Something to log and print";
int main()
{
//...
PRINT ("Something to print");
}
-Sharad
应该是 -
#define PRINT（xxx）std :: cout<< XXX; \
out1<< xxx;
Should be --
#define PRINT(xxx) std::cout << xxx; \
out1 << xxx;
