What does the basic structure required by a structured program not include?
Article Introduction:The basic structure required by a structured program does not include "GOTO jumps". Structured programming is the basic principle for detailed design focusing on module function and process design. It has three basic structures: sequential structure, branch structure and loop structure, excluding goto jumps; goto jumps are only for branch structures. One, and also a keyword. The goto statement is usually used in conjunction with conditional statements and can be used to implement conditional transfers, form loops, and jump out of loop bodies.

What are the three basic structures of structured programming in C language?
Article Introduction:The three basic structures of structured programming in C language are sequential structure, selection structure and loop structure. The sequential structure is top-down and executed sequentially. The selection structure controls the flow of the program based on the results of the judgment. The loop structure is used to describe the problem of repeatedly executing a certain algorithm.

How to convert a structure into Map in golang
Article Introduction:In Golang, converting a structure into a Map is a common operation. Map is a data structure corresponding to key values, which facilitates us to query, delete, update and traverse data. In this article, we will discuss how to convert a struct to a map in Golang. The following are the detailed steps: Step 1: Define a structure First, we need to define a structure to store data. In this article, we will define a structure named Person to represent a person’s relevant information.

Optimize loop structures in PHP programs
Article Introduction:When writing PHP programs, loop structures are a very important part, which can help us process data quickly and efficiently. However, in some situations that require a large amount of data processing, the loop structure may become a bottleneck of the program and reduce the operating efficiency of the program. Therefore, optimizing loop structures is one of the important means to improve program performance. This article will introduce some methods to optimize loop structures in PHP programs. Use foreach loop instead of for loop. In PHP, commonly used loop structures include for loop and foreach loop.

Java data structure and algorithm: practical optimization of microservice architecture
Article Introduction:Java Data Structures and Algorithms: How to Optimize in Microservices Architecture Introduction In microservices architecture, it is crucial to optimize data structures and algorithms to improve system performance and scalability. This article explores how to use appropriate data structures to optimize common microservices architecture patterns and provides real-world examples. Data structures arrays and linked lists: used to store and access linear data. Arrays provide fast access, while linked lists have advantages in inserting and deleting elements. Stacks and queues: Last-in-first-out (LIFO) and first-in-first-out (FIFO) structures for temporary storage of data. Hash table: Use key-value pairs to store data and provide fast retrieval. Trees and graphs: used to store and navigate complex data structures. Real example scenario 1: Storing authentication information in the gateway microservice

How to initialize member variables of a structure in go language
Article Introduction:Initialization method: 1. Use the "ins := structure type name {field 1: value, field 2: value,...}" statement to initialize, which is suitable for selectively filling structures with many fields; 2. Use "ins := structure "Body type name {value of field 1, value of field 2,...}" statement initialization is suitable for structures with fewer fields.

What are the three basic structures of structured programs?
Article Introduction:The three basic structures are: 1. Sequential structure, each operation in the program is executed in the order in which they appear; 2. Selection structure, there are branches in the processing steps of the program, and one of the branches needs to be selected for execution according to a specific condition. ;3. Loop structure, the program repeatedly performs one or more operations until a certain condition is false [or true] before the loop can be terminated.
