Check if Array contains Specific Element in Go

Check if Array contains Specific Element

To check if array contains a specific element in Go, iterate over elements of array using a for loop, and check for the equality of values using equal to operator. If there is a match, we may stop the search and conclude that the element in present in the array.

Example

In the following program, we take an integer array arr of size 5. We check if the element 40 is present in this array.

example.go

package main

import "fmt"

func main() {
	arr := [5]int{10, 20, 30, 40, 50}
	var element int = 40

	var result bool = false
	for _, x := range arr {
		if x == element {
			result = true
			break
		}
	}

	if result {
		fmt.Print("Element is present in the array.")
	} else {
		fmt.Print("Element is not present in the array.")
	}
}

Output

Element is present in the array.

Conclusion

In this Golang Tutorial, we learned how to find if an array contains a given element, with the help of example programs.
