Try to avoid operator[] unless you intend to change the content of the map. It has to lock the map for writing, which excludes other threads from accessing the map. Implementations of R-W lockSep 27, 2021 · The insertion is discussed in this article. 1. Using insert (): Insert function is used to insert the key-value pair in the map. After insertion, the reordering of elements takes place and the map is sorted w.r.t the key. This function is implemented in 3 ways: insert (pair): This function inserts the pair in the map. You can enter items into std::map using the insert () function. Remember that the std::map keys must be unique. So, it first checks whether each key is present in the map. If it's present, the entry will not be inserted, but it returns the iterator for the existing entry. If it's not present, the entry is inserted.Around the time C++17 was being standardized I saw magical terms like "discriminated union", "type-safe union" or "sum type" floating around. Later it appeared to mean the same type: "variant". Let's see how this brand new std::variant from C++17 works and where it might be useful. The Basics In my experience, I haven't used unions much.Jun 15, 2021 · C++ map Explained (With Examples) C++ std::map is an associative container, allowing you to store keys associated with values, for easy and efficient retrieval.
