I have checked my code with cppcheck and it says that my char outStr[256] field should be initialized in constructor's initializer list. warning: Member variable 'outStr' is not initialized in the constructor. This field is only used in this method: const char* toStr(){ ...
In the previous lesson, we introduced the concept of container classes, and showed an example of an IntArray class that holds an array of integers: #include <cassert> // for assert() #include <iostream> class IntArray { private: int m_length{}; int* m_data{}; public: IntArray() ...
