Structure can systematically link several variables together, which can solve a lot of trouble in some examples. Examples are as follows: To register patients for medical treatment, prepare a procedure to arrange the registered patients in the order of medical treatment according to the following principles: Elderly (age ≥ 60)   Age) ...

1, Foreword The sequential storage structure of linear table (such as array) has continuous storage space, so we don't have to worry about the logical relationship between elements. The biggest advantage of linear table is that it can quickly access the elements at any position in the table. The disadvantage of linear table sequential storage ...

Attach the program effect first: Adjacency table: Adjacency matrix, that is, a two-dimensional array is used to store the relationship between each vertex and the corresponding edge. For example, if there are edges between two vertices, set the subscript corresponding to this two-dimensional array to a non-zero value. As shown below: Undirec ...

preface In C language, file is an important concept in programming. The operating system manages data in the unit of files. Although there may not be many places to use files in the future, files are still an indispensable part of C language. Well, no more nonsense. Let's get straight to the point. 1, What is a file Concept: files on dis ...
