In programming, we may need to generate specific input data multiple times. Sometimes, simply displaying data on the console is not enough. The data to be displayed may be quite large, while the console can only display a limited amount of data, and due to the volatile nature of memory, it cannot repeatedly fetch programmatically … Read more
Review of Basic Concepts of References A reference is essentially an alias for an existing variable. When we create a reference, we are essentially giving another name to a variable, and both point to the same memory address. For example: int num = 10; int& ref = num; Here, ref is a reference to num. … Read more
C++ Functions: Definition, Invocation, Parameter Passing, and Return Value Analysis C++ is a powerful programming language, and functions are a very important component of it. Functions allow us to encapsulate a piece of code for reuse when needed. In this article, we will delve into the functions in C++, including how to define, invoke, pass … Read more
Previously, we discussed a lot about MATLAB vectors and matrices. In this chapter, we will discuss multidimensional arrays. In MATLAB, all variable data types are multidimensional arrays; a vector is a one-dimensional array, and a matrix is a two-dimensional array. First, let’s look at some special types of arrays. Special Arrays in MATLAB In MATLAB, … Read more
Hi, friends! I’m Hui Mei 👩💻, and today we will explore a classic yet often misunderstood concept in C++—the **inline function**. If you’re new to C++, you might be confused about this keyword: is it a “black technology” for performance enhancement or a trap that’s easy to fall into? In this article, I will analyze … Read more
Hello everyone, today we are going to talk about the “static star” in C++ — <span>static</span>. This keyword seems simple at first glance, just six letters, but it plays multiple important roles in C++, involving different semantics for variables, functions, and classes. If you still regard <span>static</span> merely as a synonym for “static variable”, then … Read more
