Advanced C++Syntax - Lesson 5 - Character Arrays: Basics

This course focuses on character and string processing in C++language, and explains the definition, use and difference of character variables and character arrays. The character encoding and character array storage methods, such as one-dimensional character array and two-dimensional character array, are discussed. Through actual coding cases, guide learners how to use the for loop and string length function to input, process and output strings, including processing string input with spaces. This article focuses on the usage of the getline function to read strings containing spaces, and how to count the length of input strings through the string length function. The teaching method is suitable for beginners and developers who need to deeply understand the C++character and string processing mechanism.

Learn C++from Teacher Wang: divide and conquer algorithm

Divide and conquer algorithm is a powerful skill, which plays a key role in solving complex problems. This abstract focuses on the application of divide and conquer algorithm in C++, emphasizes its characteristic of decomposing large problems into small problems that can be solved independently, and points out the importance of combining function design. Recursive functions are commonly used in this process. They can be combined with parallel computing to make tasks such as array sorting and searching more efficient. Typical practical application scenarios include database query and web crawler. In these scenarios, large-scale data processing becomes easier to manage through divide and conquer algorithm, and processing speed is also improved. This algorithm not only reduces the complexity of the problem, but also shortens the solution time. For C++developers who want to improve the efficiency of data processing, it is crucial to master the divide and conquer algorithm.

Say goodbye to the boring and difficult array of c++

The course focuses on the basic knowledge of arrays in C++, including one-dimensional and two-dimensional arrays. This paper expounds that array is an effective structure for solving the storage and processing of a large amount of data, especially when dealing with element sets with the same data type. This paper introduces in detail the definition and use of arrays and their combination with the for loop, and emphasizes that arrays can only store data of the same type. Through classroom cases, this paper demonstrates how to use arrays to store score data and calculate the total score and average score, showing its practical application in simplifying code and optimizing programs. This content is suitable for entry-level developers and learners who have some knowledge of C++syntax.

C++algorithm solves maze problem

The video content covers the application of C++language in maze solving, explaining how to define a two-dimensional array to represent the maze, and find the exit through depth first search (DFS) and breadth first search (BFS) algorithms. Depth first search focuses on exploring unknown paths, while breadth first search is progressive layer by layer to ensure that the shortest or all possible paths are found. This process not only includes algorithm selection and application, but also involves path recording and backtracking technology. It provides valuable practical guidance for programming enthusiasts, algorithm learners, C++developers or those interested in solving practical problems.

The United States has banned MATLAB from Chinese universities for nearly four years. Has the domestic substitution been completed?

In recent years, due to changes in the external environment, China's high-end industrial software is facing challenges from international technical sanctions and supply disruptions. MATLAB is a software platform widely used in industry and education. The supply failure event has prompted China to urgently seek alternative solutions. In this process, open source software and Python and other programming languages have shown their potential and become some alternative options. However, the uniqueness of MATLAB lies in its powerful ecosystem and specialized engineering model library, which are not easy to copy. However, some Chinese enterprises, such as Suzhou Tongyuan, are developing domestic software mworks through cross field cooperation, and are committed to filling this gap. The software has been applied in many important industrial fields, supporting the design and simulation of large projects such as large aircraft and aeroengines, and is actively moving towards complete replacement. This effort shows the potential of domestic software in digital transformation, and also provides new opportunities for engineers and enterprises.
