If you try to store any non- nil value into an element of the bool-vector, the effect is to store t there. As with all arrays, bool-vector indices start from 0, and the length cannot be changed …

Try changing int a [n]; with std::vector a (n);. What your trying to do is illegal in C++ as your creating a static array. And to add one to the array, use a.push_back () method by pushing back the required data to the end of the array. – D-RAJ Sep 27, 2024 at 12:11 Add a comment 1 Answer Sorted by: 1 WebJan 19, 2024 · The vector class is a partial specialization of vector for elements of type bool. It has an allocator for the underlying type that's used by the specialization, which provides space optimization by storing one bool value per bit. Syntax C++ template > class vector Remarks
