"Go language Combat" reading notes, not to be continued, welcome to sweep code attention flysnow_org to the public, the first time to see follow-up notes. An interface is a convention, which is an abstract type, unlike the specific types we see, such as int, map, slice, and so on. The specific type, we can know what

This is a created article in which the information may have evolved or changed. For beginners of our go language, we like to learn to write small code while learning. After each write, we all want to see the results of the program, although the Go run tool is often easy to run and can see the results directly, but is it annoying to repeat this command every tim

Init () methodIf you want to do some initialization work in a go file, you can put the code in the Init () method.The init () method is executed first.// initializationof package}Note: It is not an input parameter and a return parameter.Identifier first letter case sensitivityWhen identifier (e.g. Constant,variable,type,function,struct field, ...) The first letter of the name is capitalized, which means that the identifier is visible outside the packa

The work of the C/S model, what is done is to send data to the server, but the development phase will encounter the loop test of the program itself, need to use a simple server to verify the correctness of the data sent. Write software in C + +, run test with Python, this time also just see go language, so have to have demo. The following three sets of programs implement the same functionality, here is a s

This is the third article, which mainly introduces heap and escape anal

The go language is a door-strong type language and therefore causes a lot of problems, interface{} any type cannot be arbitrarily converted to another type To make type conversions, you need to make a type assertion Sample code: Convert Project Main.go Package main import ( "FMT" ) func main () { var e interface{} e = Switch V: = E. (type) {case int

Server-side project, to take into account performance issues, before using the company-based framework of PHP, performance bottlenecks, after investigation, decided to use go. Because a key module was already implemented using C + +, you plan to use go as an HTTP container to combine go and C + + modules.In the online research and integration program,

, The interpreter (interpreter) needs to read the source code that we wrote and convert it to the target (object), which is then run by the computer. Because each execution of the program is more than the compilation process, so efficiency has decreased.The advantage of using scripting languages is that they are mostly run at a higher level than the compiled language and can easily handle objects such as files and directories, and the disadvantage is
