So line 30 will be included c++ practice linkUsing everything you learned try to do these: simple ArrayList class (try adding these features one by one) class field should have: size, capacity should use a template and namespace Default size #define size 4 Constructor should either take an list with values, or nothing and just create an empty array of default size. methods: constructor/deconstructor get(int index) edit(int index, T val) double() doubles the array append(T val) print() If you want more you can write sample classes for stacks, queues, trees, etc.
