List of data types in Golang

 



index Description
1 Type: int8
8-bit signed integer
2 Type: int16
16-bit signed integer
3 Type: int32
32-bit signed integer
4 Type: int64
64-bit signed integer
5 Type: uint8
8-bit unsigned integer
6 Type: uint16
16-bit unsigned integer
7 Type: uint32
32-bit unsigned integer
8 Type: uint64
64-bit unsigned integer
9 Type: int
Both in and uint contain same size, either 32 or 64 bit.
10   Type: uint
Both in and uint contain same size, either 32 or 64 bit.
11 Type: rune
It is a synonym of int32 and also represent Unicode code points.
12 Type: byte
It is a synonym of int8 .
13 Type: uintptr
It is an unsigned integer type. Its width is not defined, but its can hold all the bits of a pointer value.
14 Type: float32
32-bit IEEE 754 floating-point number
15 Type: float64
64-bit IEEE 754 floating-point number
16 Type: complex64
Complex numbers which contain float32 as a real and imaginary component.
17 Type: complex128
Complex numbers which contain float64 as a real and imaginary component.
18 Type: boolean
They are boolean types and consists of the two predefined constants: (a) true (b) false
19 Type: string
A string type represents the set of string values. Its value is a sequence of bytes. Strings are immutable types that is once created, it is not possible to change the contents of a string. The predeclared string type is string.

CRUD with Golang

  Overview this blog will be about a  basic crud app with golang .   this app will provide API to store, update, delete information . you need to know the basics of golang to understand this project. if you do not have the basics knowledge  about golang I would suggest you to read my previous blog.  I have uploaded my code in  GitHub. click the link to clone or download this project  I am going to talk about the topic below. Project setup Data handling controller Project setup  Initiate mod and set up project as per golang. if you don't know how to setup golang project i would suggest you to have a look at my blog  Creating a project with golang . this is a really short blog. you will have a quick over view of how to setup a project with golang.  so now that you have setup the project then the folder structure will be as below. Data Handling data store, delete and update will be handled in the user module. code is given below  package moduls import ( "errors&quo

Primitive data type of Golang

Overview In this blog I am going to talk about the date types and variables in go. and the topics bellow  Declaring and initializing variables   explicit initialization of variables   implicit initialization of variables complex data type list of data type Pointer pointer operator dereferencing operator address of operator Constant Iota and constant expression Declaring and initializing variables there are 2 ways you can declarer and initialize a variable they are explicit initialization variables  implicit initialization variables  Explicit initialization of variables  in this way you have to tell the compiler every thing you need to declare a variable. var i int i = 20 var j int = 3 fmt.Println(i,j) var f float32 = 32.233 fmt.Println(f)  in this way we are explicitly telling what will be the input type for that variable. Implicit initialization of variables  in this way of declaring a variable. we don't have to tell the compiler what type of data it will take on that

Creating a project with Golang

Overview    You can run a go file with out making a project. But the standard way to use go is to create a project or you can call it a space where you will be putting your go code, on the other hand it is a work space, but in Go Lang we call it module. In Go Lang modules are the official way of organize go code. in this blog I am going to explain the way you create a model and first hello world with that project. Explanation To Module you need to run the command bellow go mod init <module name>  If you can see I have named my module github.com/TahimFaisal/golang. the name of the module is called module initializer. this is the standard way of initialization. And for the go get command it will it will know where to go and get the mod if it cannot find the mod locally.  Okay, soon after you ran the command you will get a file named go.mod in your working directory  it will be having module initializer and the version of go your using.     now create a main.go file and write
