my_array exercise

In your clone of this repository, find the 6.1-my-array exercise and list the files:

$ cd archer2-cpp/exercises/6.1-my-array
$ ls
Makefile  README.md  my_array.hpp part1.cpp  part2.cpp  part3.cpp  test.cpp

my_array.hpp contains a partial implementation of an array class. You need to implement the appropriate constructors, assignment operators, and destructors to control the allocation and deletion of memory over the object’s lifecycle.

part1.cpp, part2.cpp, and part3.cpp contain examples using the my_array class that you can use to check your implementation and understanding.

For each part (e.g. part1), you can compile by running:

$ make part1
g++ --std=c++17 -I../include -c part1.cpp -o part1.o
g++ part1.o -o part1

Then run the example using:

$ ./part1
     Constructing: 0x2300eb0 [x] 
       Destroying: 0x2300eb0 [x] 
       Destroying:         0 [default]

Once you have completed all the parts, test.cpp contains some basic unit tests to check your implementation. You can compile and run with:

$ make test && ./test
g++ --std=c++17 -I../include -c test.cpp -o test.o
g++ test.o -o test
===============================================================================
