Life is all about decisions and repeat your routine

Life is all about Decisions and repeat our routine is an excellent idea which i show you within a moment. Everyday we take so many decisions based on environment conditions, circumstances. Each decision based on cause and effect philosophy. Programmer are wizards who create own world with data and structures. Without data or structure our world is nothing.

Conditions: Conditions help us to take decision based under certain circumstances, such as if a number divisible by 2 at least two times then it's said to be double even.

package main
import (

func main() {
const divisible =2
var even int = 4

if even%divisible == 0{
n := even/divisible
n /= divisible

if n ==1 {
fmt.Println("Doubly Even") 


If you're a developer then you you know this code quite different from other languages syntax. In most languages, you see like this "if (condition)". Yeah it's different but this language compilation power i like most. That's why i like this language. 
        even%divisible == 0  
Always remember taking modules only applicable on integers. Try with float and complex.

Repeat :
golang provide one way for repeat task such iterating array i index. For loop is only choice you have.
For loop in various flavours, we discuss one by one.
      Simple For Loop:
        var count int = 0
for i := 0; i < 5; i++{
fmt.Println(count) }
      Little Complex flavour:  
        var arr = [3]int{0,1,2}
for i := 0; i < len(arr); i++{
                  var arr = [3]int{0,1,2}
          arr is the name of array 
          [3] represent size of array
         {0,1,2} inside anything in these braces called values 
         %d represent integer type
          %c represent character type
          %T represent type
          %v represent verbose
          %f represent float
          %o represent octal

      Complex Loop:
       var arr = [3]string{"apple","mango","cherry"}
for i,v := range arr{
fmt.Printf("iterate:%d value:%s\n", i, v)
             i, v := range arr
   This line give you real flavour of chocolate in your recipe. Always remember range return two values one called iteration and other called value. In further topics , you understand more when you create own function similar like range. If you don't need v then 
     for i , _ := range arr 
 "_" placeholder tells compiler value don't need for this operation. Placeholder come from scala language, but this is our secret spell use it wisely.  
       var key byte = 'x'
switch key {
case 'x':
case 'o':
fmt.Println("no found")

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.    


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
