함수에 전달 된 인자를 뿌리는 방법?

허접하지만, 만들어 본 겁니다.

안 좋기는 하지만 필요한 만큼, 템플릿을 추가하시면 될 겁니다.

#include <iostream>

#define PRINTARGUMENTS(...) PrintArguments(std::cout, __func__, __VA_ARGS__)

template <typename FuncName, typename First>
inline void PrintArguments(std::ostream& os, FuncName funcName, First a)
{
    os << funcName << " : " << "arg1 = " << a << std::endl;
}

template <typename FuncName, typename First, typename Second>
inline void PrintArguments(std::ostream& os, FuncName funcName, First a, Second b)
{
    os << funcName << " : " << "arg1 = " << a << ", arg2 = "<< b << std::endl;
}

template <typename FuncName, typename First, typename Second, typename Third>
inline void PrintArguments(std::ostream& os, FuncName funcName, First a, Second b, Third c)
{
    os << funcName << " : " << "arg1 = " << a << ", arg2 = "<< b << ", arg3 = " << c << std::endl;
}

void TestFunction(int a)
{
    PRINTARGUMENTS(a);
}

void TestFunction2(int a, const char* b)
{
    PRINTARGUMENTS(a, b);
}

void TestFunction3(int a, double b, bool flag)
{
    PRINTARGUMENTS(a, b, flag);
}

int main(void)
{
    TestFunction(10);

    TestFunction2(4, "Oh, hell yeah~");

    TestFunction3(8, 91.358, false);

    return 0;
}
