Submitted by Nidhi, on March 07, 2021

Problem Solution:

In this program, we will create an integer array and initialize it with few elements. Here, we will print the prime numbers from the array and print them on the console screen.

Program/Source Code:

The source code to print the prime numbers from an integer array is given below. The given program is compiled and executed successfully.

// Golang program to print the prime numbers
// from an integer array

package main

import "fmt"

func main() {
	arr := [...]int{11, 13, 15, 17, 19, 21}

	var flag int = 0

	fmt.Printf("Prime Numbers: \n")
	for i := 0; i <= 5; i++ {
		flag = 0
		for j := 2; j < arr[i]/2; j++ {
			if arr[i]%j == 0 {
				flag = 1
				break
			}
		}
		if flag == 0 && arr[i]>1 {
			fmt.Printf("%d ", arr[i])
		}
	}
}

Output:

Prime Numbers:
11 13 17 19

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created an array arr initialized with few elements. Then we found & print the prime numbers from the array and printed them on the console screen.
