QUESTION

Default initialization of member variables or add more constructors? Best practice for creating classes?

Asked 2021-May-30 at 16:06

Following a tutorial on learncpp.com which discusses declaring member variables outside of constructors. However in previous lessons the author mentions that minimizing the amount of constructors is optimal and can be done by using default values in the parameters of a constructor. This is confusing to me because suddenly there are two places to give default values, directly where you define your member variable, and in the parameter of the constructor. Additionally, it seemed like the whole point of defining default values outside of the constructor was to prevent redundant code because "if you update the default value for a member, you need to touch each constructor".

Here's the example used:

I was reading Chapter 8 of the "Modern C++ Programming Cookbook, 2nd edition" on concurrency and stumbled upon something that puzzles me.

The author implements different versions of parallel map and reduce functions using std::thread and std::async. The implementations are really close; for example, the heart of the parallel_map functions are

I'm trying to make a program that moves a file (like file.txt) specified by the user to a directory that he also specifies. I tried using the move() function, however I don't quite understand it yet, so I tried with the rename() function and used this site's code as help.

First off, don't double up on the slashes when typing them in at the command prompt at runtime, if that is what you are doing. Escaping slashes only applies to string literals in code, not runtime data.

That said, you are not allocating enough memory to hold the user's input. When initialized with " ", your oldDir[] and newDir[] arrays are each only 2 chars in size. When you drop the " ", the compiler no longer knows how large to make the array, since you are not telling it which size to use.

You need to handle the arrays more like this instead:

The this is implicitly given, and it is often a matter of style whether to write it explicitly or not. In your case I'd say that it does not improve readability.

In other cases, however, it makes sense or is even necessary to explicitly write this in order to avoid naming conflicts between local variables and data members. Consider, for example, the following program:

C++ Iterator range using pointers to an array

Asked 2019-Apr-30 at 22:32

Question

I do not want to pass the size of the array as an index parameter.

For my merge_sort, I want to optimize my parameters using the iterator range concept. I can't seem to figure out how to deference the iterator range and access my array. I can deference to access the indices like low and high in recursive_merge_sort, but there does not seem to be an intuitive way to access the array itself. I've been using this great guide on C++ Pointers and Arrays as a starting point.

My Merge Sort C++11 C++17 question brought this concept to light and I like the idea of using iterator ranges to reduce the number of parameters for my sort.

Code

Iterators are modeled to act like pointers. They have the same type of overloaded operators: dereferencing and increment at the very least (some also have decrement, random access, etc.).

The most advanced iterator interface is random access, which functions exactly like a raw pointer (by design).

So all (raw) pointers are basically random access iterators into a C-style (contiguous) array. Look at the following to visualize begin/end iterators for a C-style array:

Variables are not the only thing that main memory stores. In fact, when you run a program, your operating system reserves some space (called address space) for the process in charge of running your executable file.

The assembly code generated by the compilation is stored in a section (the .text section), the data in (you don't say) the .data section, static variables initialized to 0 in the .bss section and so on. Strings, for example, are usually stored in read-only sections (.rodata).

So the answer is no, every program, when running, has to use memory.
