Post Views: 30 As the core feature of the Go language, Goroutine is the key to lightweight concurrency. It is lighter than traditional operating system threads and has lower creation cost. The default initial stack is only 2KB and supports dynamic expansion, which allows developers to easily achieve high concurrency programming. For beginners who are new to Go concurrency, understanding…

The first pit: depend on download failure (502 bad gateway), you can refer to:GO TOUR slicing exercise to run the full record of the pit on the pit (from error report to successful operation) as shown in Figure 1 Error message: Error cause: Solution: 3. The second pit: the IDE still…

Post Views: 29 In Go language, errors are not an exception, but a value. By implementing the Error interface, we can create custom error types with rich context information. This article will combine Go Tour’s ‘exercise: errors’ exercise to explore how to implement a square root function that supports negative number detection, and reveal the ‘infinite recursion’ pit that is…

Post Views: 63 Following the previous articleMaps word counting exercisesAfter this, another classic exercise in the introduction of Go language – using closure to implement the Fibonacci sequence generator. This question can not only consolidate the core usage of closed packages, but also deeply understand the characteristics of ‘function as the return value’ in the Go language. This article will…

Post Views: 115 As a basic exercise for the entry of Go language, the use of MAPS (mapping) is one of the key knowledge points, and word counting exercise is a classic case of consolidating MAPS usage. This article will record in detail the implementation process, core ideas, code analysis, and key knowledge points involved in the exercise. 1. Description…

Post Views: 89 Recently, when I was doing the slices practice of the official go to the go, I encountered a series of dependencies download and running errors, and after tossing, I finally succeeded in running through. I have sorted out the complete stepping process and solutions, hoping to help those who practice Go Tour locally like me, and avoid…

Post Views: 44 1. When learning the official Go tutorial a Tour of Go, I encountered a very classic exercise:Implement a square root function sqrt(x). as shown in Figure 1 This exercise involves not only Go’s loops and functions, but also introduces a very important numerical calculation method:Newton iteration method (Newtons method). This article will demonstrate how to get from…

Post Views: 31 1. In VS Code, Go reports an error: Main redeclared in this block. The reason is that there are multiple main functions in the directory. as shown in Figure 1 2. Reorganize an exercise directory structure scheme of A Tour of Go to ensure that each exercise can run go run main.go independently, and there will be…
