One problem with dynamic arrays is that they don't carry around their size. Create a structure, DynArray which uses a unique pointer for a dynamic array (data), and an int for the size and сараcity. dynarray.h 1 #ifndef DYNARRAY_H 2 #define DYNARRAY_H 3 4 #include 5 #include <пелпогу» 6 7 | Define the DynArray structure here 9 std::ostream& operator<<(std::ostream& out, const DynArray& a); 10 std:istream& operator>>(std::istream& in, DynArray& a); 11 DynArray makeDA (int capacity); 12 13 #endif memory.cpp 1 #include 2 #include 3 #include "dynarray.h" 4 using namespace std; int main() 8. 9 10 cout « "Array capacity: "; int capacity; cin » capacity; 11 auto a = makeDA(capacity); cout « "Enter up to " « capacity <« " numbers: "; cin » a; 12 13 14 15 16 17 } cout « "a->" <« a « endl; CodeCheck Reset 567 C
