In the previous tutorial, we explored concurrency and the differences between concurrency and parallelism. This tutorial will show you how to use Go Association (goroutine) to implement concurrency in the Go language. # # What is

Go does not have a native interface library, so it cannot be used to write GUI interfaces directly. But recently the internet has sprung up a lot of mature, useful third-party interface library. Using them, you can also write a C #, C + + interface. and more efficient.About Walk Interface Library (official introduction): Walk is a Windows Application Library suite for Golang, which is used primarily for desktop GUI development, but there are

What is go?Go is a compiled system programming language with concurrent support and garbage collection designed to create a well-balanced programming language with high performance and efficient development of dynamic languages in statically compiled languages.What are the main features of go?* Type safety and memory security* High concurrency with very intuitive

1. multi-value return In C/C ++, if multiple values need to be returned, the pointer or reference is usually input in the function, for example Fun (int * a, int * B, int * C), but in go, if you want to return multiple values, you only need to write the function as follows: 1Func test_func ()(Int,Int,Int){2A: =1;3B: =2;4C: =3;5 6ReturnA, B, C;7} Finally, the function returns A, B, and C in sequence. This is actually already available in Lua,
