stl::map에 에서 이미 존재하는 항목을 update하기 위해서는 다음과 같이 사용한다. #include #include void main() { std::map test1; test1[0] = 1; test1[1] = 2; test1[1] = 3; for (auto it = test1.begin(); it != test1.end(); it++) { printf("%d %d\n", it->first, it->second); } } 배열에 값을 할당하듯 사용하면 해당되는 key 값이 없으면 map에 새로 추가되고, 해당되는 key 값이 없으면 map에 있는 해당 항목 값이 변경된다. 그런데 stl::map 구조를 pointer로 선언했을 때는 배열 사용하듯 할 수가 없고 값의 변경을 위한 함수가 따로 ..

Since I am writing the program analyzer with Python and C++, I first tried to find a python name unmangler. But so far, there is no python unmangler. There was a discussion about the need of the python unmangler script at OpenRCE. Anyway, I planed to write a C function that..

I met a few problems while building the elsa package. The first problem was a sort of preprocessor syntax error. I found the following code snippet. /* The contents of this function are C++ specific, so the () macro is not used. The ..
