STL–vector container (construction, traversal, insertion and deletion, capacity size, data access, dynamic expansion, etc.)

vector Foreword In the past few days, I have used STL a lot when writing code, and I have also felt the power of STL, so I reviewed the content of STL again, and summarized and extracted some basic things and important content. This is a vector article . C++’s STL provides us with many […]

C language pointer array pointer traversal

Pointer array pointer traversal Refer to the summary of knowledge about C language novices turning into monsters 1. All data in the computer must be put into memory, and different types of data occupy different spaces, such as int 4 bytes char 1 byte 2. Pointer (address): Each byte in memory has its own address, […]

Algorithm Issues in Communication Networks Experiment 4-Depth-First Algorithm and Breadth-First Algorithm (Node Traversal)

Experiment 4 Algorithm issues in communication networks-depth-first algorithm and breadth-first algorithm (node traversal) 1. Introduction In communication networks, node traversal is an important task that helps understand the topology of the network, identify potential problems, and perform various analyses. Depth-first search algorithm and breadth-first search algorithm are two commonly used graph traversal methods, which can […]
