In C++, when initializing an array, elements are initialized in row-major order. And when traversing an array, it is most efficient to access elements in the order they are laid out in memory.Initializing two-d
One important point to note is that C-style strings follow the same rules as C-style arrays. This means you can initialize the string upon creation, but you can not assign values to it using the assignment operator after that! charstr[]{"string"};// okstr="rope";// not ok!

The configuration array consists of name-value pairs that are used to initialize the properties of this form. $model CModel the model object associated with this form. If it is null, the parent's model will be used instead. $parent mixed the direct parent of this form. This could be ...
Finally, sticking to array initializations saves you and your readers the conceptual overhead of switching between pointer initializations and array initializations, depending on if you need mutability or not. Just always initialize string literals as arrays, and keep it simple. Where possible, use si...
