Go Foundation

Golang Language is pretty good language. Most of us start our career from C the mother of all Languages. If you build a house you know know to build that.
      Components of house
            1. Variables
            2. Constants
            3. Functions
            4. Conditions
            5. Loops

Variables
      Let start with Variables.
In Golang there're so many types of variables int , float , string, byte , complex , pointers etc.




In go-lang integers exit in five classes. Each class has own properties
      int
      int8
      int16
      int32
      int64
                Int
         integers range start from 0 to 65535.
                 Int8
        integers of this class start from 0 to 2^8.
                Int16
        Similar like int8 it start with 0 to 2^16.
if you had write a code you know integers have two types
         signed and unsigned
There're so many operations on integers such as addition, increment, less than etc. I will show you in a moment.
         var name type = value
         var a int = 0
         var b int = 3
         fmt.Println("c:", a+b)  // 3
             Let me ask you if two different classes of integers operate what's the output
             var a int = 9
             var b int8 = 5
             fmt.Println(a+b)

Please share your answer in a comment section
             In go local variables and global variables are most important. If a variable declare as a local then it's life story little short. While package variables called global variables. They initialize with Upper case Letters. The reason behind that they can access through other files too.
            There's is another flavour in go to initialize local variables but more details in any other topic.
        In  Short name declaration programmer can write name of variable, then ":=" value. This value tells variable type either it's integer, float etc.
         
             a := 0 // int
             c := 3.4    // float32, float64
Gopher's are best

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
