How to get the Index of Specified Element in an Array in Go

How to get the Index of Specified Element in an Array in Go ?

Answer

To get the index of a specified element in an array in Go, you can iterate over the array and check each element.


✐ Examples

1 Index of Element 30 in Integer Array

In this example,

  1. We create an integer array arr with values 10, 20, 30, 40, 50.
  2. We iterate over the array and check each element if it's equal to 30.
  3. If the element is found, we print its index.
  4. If the element is not found, we print a message indicating it's not in the array.

Go Program

package main

import (
	"fmt"
)

func main() {
	arr := []int{10, 20, 30, 40, 50}
	specifiedElement := 30
	found := false

	for index, element := range arr {
		if element == specifiedElement {
			fmt.Printf("Index of specified element %d is: %d\n", specifiedElement, index)
			found = true
			break
		}
	}

	if !found {
		fmt.Println("Specified element not found in the array")
	}
}

Output

Index of specified element 30 is: 2

2 Index of Element 60 in Integer Array

In this example,

  1. We create an integer array arr with values 10, 20, 30, 40, 50.
  2. We iterate over the array and check each element if it's equal to 60.
  3. If the element is found, we print its index.
  4. If the element is not found, we print a message indicating it's not in the array.

Go Program

package main

import (
	"fmt"
)

func main() {
	arr := []int{10, 20, 30, 40, 50}
	specifiedElement := 60
	found := false

	for index, element := range arr {
		if element == specifiedElement {
			fmt.Printf("Index of specified element %d is: %d\n", specifiedElement, index)
			found = true
			break
		}
	}

	if !found {
		fmt.Println("Specified element not found in the array")
	}
}

Output

Specified element not found in the array
