首先,我有以下代碼: map<char*, char*> records;
// id, value are buffer variables to store the text that returns from `strcpy()`
char *id = (char*)malloc(sizeof(char*) * 20);
char *value = (char*)malloc(siz
Implementing class for disjoint sets struct Set

int parent,rank;
Set(int i):parent(i),rank(0){}
Set(const Set& s2):parent(s2.parent),rank(s2.rank){}

我不得不每次都重新創建一個映射,而不是僅僅引用已創建的映射。 這工作: void render(Scene *scene) {
map<std::string, Node*> _map = scene->getNodes(); // I don't want recreate the map every time. It is slowing down the render funct
