Like other programming languages, in C++, an array is a collection of similar types of elements with contiguous memory locations. In C++, std::array is a container that encapsulates fixed-size arrays. In C++, array indexing starts at 0. We can only store a fixed number of elements in a C++ array. In C/C++ programming languages or … Read more
1. Understanding MATLAB 1. Overview of MATLAB (1) In universities in Europe and America, MATLAB has become a fundamental teaching tool for courses such as linear algebra, automatic control theory, digital signal processing, time series analysis, dynamic system simulation, and image processing. It has become a basic skill that undergraduate, master’s, and doctoral students must … Read more
Click the blue words Follow us Function Pointers Functions also have their own addresses; the function name/&function name is the address of the function. 1.1 Basic Form In the study of array pointers, we learned that int arr[5];int (*pa)[5] = &arr;//pa is an array pointer The type of pointer variable pa is int(*)[5]. So what … Read more
An array is a collection of data items of the same type stored at contiguous memory locations. Arrays are derived data types in C that can store primitive data types (like int, char, double, float) as well as derived data types (like pointers, structures, etc.). Arrays are the simplest data structure, allowing random access to … Read more
The for loop in C language is used to execute a statement or a part of a program multiple times. It is often used to traverse data structures such as arrays and linked lists. The syntax of the for loop in C is as follows: for (Expression 1; Expression 2; Expression 3) { // Code … Read more
◆Key Point 1: Method to Swap Two Variable Values 1) Using a third variable (the easiest method) 2) Using addition and subtraction to swap values (commonly used in interviews **) The code is as follows: b = a – b; a = a – b; b = a + b; 3) Using bitwise XOR to … Read more
Pointer Operations Pointer operations give it powerful functionality. In addition to the dereference operation (*) and the address-of operation (&), pointers also support some arithmetic operations. For example, pointers can perform addition and subtraction, but it is important to note that pointer addition and subtraction are not simple numerical addition or subtraction; they are based … 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
“To become a master, it is not achieved overnight, unless you are a natural talent in martial arts, but such people are… one in ten thousand” —— Landlady This principle also applies to learning C language. There are indeed few people with exceptional talent in programming; most of us need to accumulate knowledge day by … Read more
“To become a master, it’s not something that can be achieved overnight, unless you’re a natural talent in martial arts, but such people… are one in a million.” —— Landlady This principle also applies to learning C language. After all, those with exceptional programming talent are few and far between. Most of us need to … Read more
