开源软件名称:SimonWaldherr/golang-examples开源软件地址:https://github.com/SimonWaldherr/golang-examples开源编程语言:Go 95.5%开源软件介绍:Go ExamplesIf you liked this project, you may also like my golang-benchmarks repository: AboutThese examples explain the basics of Golang. There will be more examples from time to time. if you like, feel free to add more Golang examples. Many thanks to all contributors. Install go(lang)with homebrew: sudo brew install go with apt-get: sudo apt-get install golang install Golang manually or compile it yourself ExamplesThe examples are divided into three levels of difficulty. The Beginner section contains very easy examples, starting with Hello World but also containing a few easy algorithms. The Advanced section uses more complicated features of Golang. Finally, the Expert section contains applications like telnet-clients or http-server (even with SSL). If you want even more Golang examples, you can take a look at my other go repositories at GitHub:
All of them are published as free and open source software. If all of this is even not enough for you, you can take a look at the following websites: BeginnerTo execute a Golang program, write Print Hello World with comments (Golang Playground) go run HelloWorld.go Print Hello World with comments (shebang version) ./HelloWorldShebang.go Declare variables and print them (Golang Playground) go run var.go Various ways (and styles) to print variables (Golang Playground) go run printf.go If statement in Golang (Golang Playground) go run if.go Hello Declare array and print its items (Golang Playground) go run array.go Declare your own functions (Golang Playground) go run function.go Do something multiple times (Golang Playground) go run for.go Read via cli provided input data (Golang Playground) go run args.go string string2 Read via cli provided input data (Golang Playground) go run input.go Or scan for it (Golang Playground) go run scan.go Read named argument input data (Golang Playground) go run flag.go Return the working directory (Golang Playground) go run dir.go Return the current time/date in various formats (Golang Playground) go run time.go Return pseudo random integer values (Golang Playground) go run random.go Concat strings in two different ways (Golang Playground) go run cat.go Modulo operation finds the remainder of division (Golang Playground) go run modulo.go Split a string by another string and make an array from the result (Golang Playground) go run split.go An example implementation of the Ackermann function (Golang Playground) go run ackermann.go An example implementation of the Euclidean algorithm (Golang Playground) go run euklid.go Submit a function as argument (Golang Playground) go run functioncallback.go A function returned by a function (Golang Playground) go run functionclosure.go A function with an unknown amount of inputs (variadic function) (Golang Playground) go run functionvariadic.go Empty interface as argument (You Don't Know Type) (Golang Playground) go run interface.go Execute Shell/Bash commands and print its output values (Golang Playground) go run shell.go Make structs (objects) which have functions (Golang Playground) go run oop.go Dependency injection for easier testing cd beginner/di
