Question

A vector data structure is a dynamically-sized array. The C++ standard library uses std::vector<T> to represent vectors. Assume a function that declares a local variable std::vector<int> v. In which memory segment is the v object located, stack, heap, or somewhere else?

Group of answer choices

somewhere else

stack

heap

Answer 1

The vector object v would be allocated in stack segment of the memory because whenever any function uses any local variable then all the variable created inside this function are stored in stack. This is because this local variable is not going to be used outside of this function that gives better memory management. Also access speed to the stack is very fast and when the function call ends it automatically deallocate all the memory declared inside the function.
