And I would also use a member variable to represent the control in MFC, e.g. an instance of CStatic for your static control. In this way, you don't need casts (which IMHO should be used as few as possible), and the code becomes much more clear, e.g.:...
This method allows you to store elements of the same data type in contiguous memory locations. When dealing with structs, each element of the array will represent an instance of the struct. Note that this method has a limitation: the declared array is a basic object devoid of built-in funct...
Method 1: Returning a Pointer to a Dynamically Allocated Array Method 2: Using std::array Method 3: Using std::vector Conclusion FAQ Returning an array from a function in C++ can be a bit tricky, especially for those new to the language. Unlike some other programming languages, C++...
as we do, to refer to the Z component of the actual cross product of your 2D vectors extended to 3D. In some code bases they also call this "the determinant”, which is an operation you can do on a matrix

The following methods can be used in order to represent the density of a continuous variable. Note that here we represent the same data as in the previous figure, this time with Horsepower as X (over which the densities are represented), and separating the region of origin with subplots. ...
In this step-by-step tutorial, you'll learn the fundamentals of descriptive statistics and how to calculate them in Python. You'll find out how to describe, summarize, and represent your data visually using NumPy, SciPy, pandas, Matplotlib, and the built
When you’re indenting your code, the official Python style guide called PEP 8 recommends using 4 space characters to represent one indentation level. Most text editors that are set up to work with Python files will automatically insert 4 spaces if you press the Tab key on your keyboard. You...
This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie for these resources, and the kernel’s job is to allocate resources fairly. The kernel itself is al...
(their coordinates are written to the 'vertices' array), as well as dividing of cube edges into triangles which are enumerated and saved in the 'indiсes' array. In total, the cube has 8 vertices, 6 faces which are divided into 12 triangles, and 36 indices enumerating the vertices of ...
