C language data structure: data representation and operation of trees and graphs
Apr 04, 2025 am 11:18 AM
C language data structure: The data representation of the tree and graph is a hierarchical data structure consisting of nodes. Each node contains a data element and a pointer to its child nodes. The binary tree is a special type of tree. Each node has at most two child nodes. The data represents structTreeNode{intdata;structTreeNode*left;structTreeNode*right;}; Operation creates a tree traversal tree (predecision, in-order, and later order) search tree insertion node deletes node graph is a collection of data structures, where elements are vertices, and they can be connected together through edges with right or unrighted data representing neighbors.

Algorithms are the set of instructions to solve problems, and their execution speed and memory usage vary. In programming, many algorithms are based on data search and sorting. This article will introduce several data retrieval and sorting algorithms. Linear search assumes that there is an array [20,500,10,5,100,1,50] and needs to find the number 50. The linear search algorithm checks each element in the array one by one until the target value is found or the complete array is traversed. The algorithm flowchart is as follows: The pseudo-code for linear search is as follows: Check each element: If the target value is found: Return true Return false C language implementation: #include#includeintmain(void){i

Integers in C: a little history
Apr 04, 2025 am 06:09 AM
Integers are the most basic data type in programming and can be regarded as the cornerstone of programming. The job of a programmer is to give these numbers meanings. No matter how complex the software is, it ultimately comes down to integer operations, because the processor only understands integers. To represent negative numbers, we introduced two's complement; to represent decimal numbers, we created scientific notation, so there are floating-point numbers. But in the final analysis, everything is still inseparable from 0 and 1. A brief history of integers In C, int is almost the default type. Although the compiler may issue a warning, in many cases you can still write code like this: main(void){return0;} From a technical point of view, this is equivalent to the following code: intmain(void){return0;}
