WebFeb 21, 2016 · Fixed size arrays for string buffers on the stack are not a problem because they keep memory on the stack, they are a problem because fixed size buffers are a fatal problem waiting to happen. But if you use C++, and declare for example a std::string or a std::vec on the stack, then what is on the stack will be actually of a fixed and small size. WebMar 11, 2024 · std::array is a container that encapsulates fixed size arrays.. This container is an aggregate type with the same semantics as a struct holding a C-style array T [N] as its only non-static data member. Unlike a C-style array, it doesn't decay to T * automatically. As an aggregate type, it can be initialized with aggregate-initialization given at most N …
