Count Array Elements in Golang

Application

Create new folder named src. In src folder, create new file named main.go as below:

package main

import "fmt"

func main() {

	var a = [5]int{11, -4, 7, 8, -10}
	result1, result2, result3, result4, result5 := count(a)
	fmt.Println("Count elements: ", result1)
	fmt.Println("Count positive  elements: ", result2)
	fmt.Println("Count negative elements : ", result3)
	fmt.Println("Count even elements: ", result4)
	fmt.Println("Count odd elements: ", result5)

}

func count(a [5]int) (int, int, int, int, int) {
	counter1 := 0
	counter2 := 0
	counter3 := 0
	counter4 := 0
	counter5 := 0
	for _, value := range a {
		counter1++
		if value > 0 {
			counter2++
		}
		if value < 0 {
			counter3++
		}
		if value%2 == 0 {
			counter4++
		}
		if value%2 != 0 {
			counter5++
		}
	}
	return counter1, counter2, counter3, counter4, counter5
}

Output

Open Terminal windows in Visual Studio Code and run command line: go run main.go

Count elements:  5
Count positive  elements:  3
Count negative elements :  2
Count even elements:  3
Count odd elements:  2
