import "fmt"

//Logger
var log = fmt.Println
var logT = fmt.Printf


// Struct Declarion
type  abcd  struct{
    a string
    b int 
    c bool
    d float64
}

func main(){
//variable declaration
var a string = "hello"
var b int = 12
var c bool = true
var d float64 = 12.34

log("a:",a,"b:",b,"c:",c,"d:",d)
 
//    collection of varible i.e Struct
abcd_value := abcd{"hello",  12,  false, 12.22}
logT("struct variables %+v\n",abcd_value)
   
   
type man struct {
    age  int
    sex  string
    name string
 
 }
       man_value := man{
         12 ,
         "M" ,
         "Your Name"}    
  
 
//   log a struc With KEy values
     logT("struct variables %+v\n",man_value)
  man_value_with_key := man{
       age: 12 ,
       sex: "M" ,
       name: "Your Name"}
   log(man_value_with_key)
}
