In this shot, we will learn how to iterate through a string in Golang.

We can use the following methods to iterate through a string:
* `for` loop
* `for-range` loop


#       
## The `for` loop method
There are two steps to follow for this method:
* Find the length of the string. 
* Use a `for` loop to get each character at the present index.

package main

//import fmt package
import(
  "fmt"
)

//Program execution starts here
func main(){

  //provide the string
  str:= "Educative"

  //iterate through the string
  for i:=0; i<len(str); i++{

    //print each character in new line
    fmt.Printf("%c\n", str[i])
  }

}

#      
## Explanation
In the code snippet above:
* In *line 5*, we import the `fmt` package.
* In *line 9*, the execution of the program starts from the `main()` function.
* In *line 12*, we declare the string `str` with shorthand syntax and assign the value `Educative` to it.
* In *line 15*, we use a `for` loop to iterate through the string.
  * We use the `len()` method to calculate the length of the string and use it as a condition for the loop.
* In *line 18*, we use the index `i` to print the current character.


#         
## The `for-range` loop method
The `for-range` loop returns two values in each iteration:
* `Index`: the index of the current iteration.
* `Character`: the character at the present index in the string.


package main

//import fmt package
import(
  "fmt"
)

//Program execution starts here
func main(){

  //provide the string
  str:= "Educative"

  //iterate through the string
  for _, character := range str {
    
    //print each character in new line
    fmt.Printf("%c\n", character)
  }
}



#          
## Explanation
The explanation is the same as the `for` loop method except for the following differences:

* In *line 15*, we use the `for-range` loop to iterate through the string.
* Since we are not using `index` returned by `range`, we can use `_` in its place.
* In *line 18*, we print each character in a new line.
