Go handle Json Perfectly

JSON abbreviation "JavaScript Object Notation". There're so many tools for structure data such as xml, Json, asn.1 and google protobuf.

XML and JSON:
writing code in a xml, so called boilerplate. Java and android use xml for project management. While json, is easy as compare to xml. Mostly use json because it's easy to play around and good choice for web application.

Code :
package main
import ( "fmt" "encoding/json")
type Books struct{ Title string  Status bool Writer string  Comments string}


func main() { var Library =[]Books{ {Title:"Lord of Rings the fellowship", Status:false, Writer:"J-J-R-Tolkien",Comments:""}, {Title:"Quantum Aspects of Life",Status: false, Writer:"Paul-C",Comments:""}, {Title:"You were born rich", Status:true, Writer:"Bob Proctor",Comments:"good book"}, } if lib , err := json.MarshalIndent(&Library,""," "); err== nil{ fmt.Printf("%s",lib) } }
Encode library provide so many sub packages json one of them, try to use it the above it just show you a demonstration. You can use Marshal or MarshalIndent for encoding your data in json.

Marshal and MarshalIndent:
  Marshal :
            lib,err := json.Marshal(Library)
        Marshal take a parameter that to be convert in my case that is Library. Json.Marshal
return value and error so you can handle it. This function have one problem encoded data are  not distinguishable. Return value similar to string. 

MarshalIndent:
           lib, err := json.MarshalIndent(&Library, "", " ")
 Again this is similar to previous function but , this function demand address of data , not itself. Second it take two parameters . Just play around

Similar like encoding, you can also decode data by using unMarshal and unMarshalIndent.

I'm thinking i will add google protobuf in my upcoming articles.

Rosicrucian cipher

In 1513 Cornelius Agrippa introduce early form Rosicrucian Cipher in his books Occult of Philosophy. Geometric and simple substitution cipher are well known ciphers      Pigpen , Freemason, Napoleon and tic tac toe ciphers in which alphabets or symbols arrange in grids.  This is an anagram, "How to reconstruct a data " lets encode the message.       Pigpen cipher , Rosicrucian and Tic tac toe Cipher                      Thank you have a good day.    

Enumerate

Golang provide  own enumerate method which is easy and very powerful. I will show you enumerate with in a sec. When i code enumerate in java, believe me i don't understand why it's used? So i never play from this card at that time, but recently when i start learning go. Now i used where it's used and why? Enumerate basically a counting method. Code   package main import ( " fmt " ) type Weekend int const ( Sunday Weekend = iota Monday Tuesday Wednesday Thursday Friday Saturday ) func main () { fmt. Printf ( " %d " ,Saturday) } If you remember adding color layer then you familiar from this code.  First i create my own type called weekend then used this type.  Iota-generator:   Things that confuse you Sunday Weekend = iota & Monday without value. Before we start Iota-generator first we understand monday without type or value         const ( c = 1 // c : 1 d      // d : 1 ) fmt.Pr

Every Object have a structure

If you start your programming career from c , then you know little about structs. Later Struct replace by classes in object oriented programming. However Go inherit from C. Structs :     With the help of structs, programmer can develop any type of structure         List        Stack        Queue        Trees        Graphs package main import ( " fmt " ) type Students struct { ID int Name string } var record Students func Id ( i int ) int { record. ID = i return record. ID } func Name ( name string ) string { record. Name = name return record. Name } func main () { var id int = 0 var name string = " ali " fmt. Println ( " id: " , Id (id), " name: " , Name (name)) } When we want to create custom type such as Celsius type Celsius float64, same with structs type Students structs except type need data type and in structs. You tells that's struct. Inside Structs
