Go Nested if Statement
The Nested if Statement
You can have if statements inside if statements, this is called 
a nested if.
Syntax
        if  condition1 { 
           // code to be executed if condition1 is true 
          if condition2 { 
              // code to be executed if both condition1 and condition2 
        are true
         
        }
}    
      
Example
This example shows how to use nested if statements:
    package main
    import ("fmt")
    
    func main() { 
        num  := 20 
        if num >= 10 {
          fmt.Println("Num is more than 10.")
          if num > 15 {
            fmt.Println("Num is also more than 15.")
           }
        } else {
          fmt.Println("Num is less than 10.")
        }
    }
    
  Result:
      Num is more than 10.
      Num is also more than 15.
