Sorting an integer array in ascending order using bubble sort in Golang

Problem Solution:

In this program, we will read array elements from the user then sort the array in ascending order using bubble sort and then print the sorted array on the console screen.

Program/Source Code:

The source code to sort an integer array in ascending order using bubble sort is given below. The given program is compiled and executed successfully.

Golang code to sort an integer array in ascending order using bubble sort

// Golang program to sort an integer array
// in ascending order using bubble sort

package main

import "fmt"

func main() {
	var arr [5]int
	var temp int = 0

	fmt.Printf("Enter array elements: \n")
	for i := 0; i <= 4; i++ {
		fmt.Printf("Elements: arr[%d]: ", i)
		fmt.Scanf("%d", &arr[i])
	}

	for i := 0; i <= 4; i++ {
		for j := 0; j < 5-i-1; j++ {
			if arr[j] > arr[j+1] {
				temp = arr[j]
				arr[j] = arr[j+1]
				arr[j+1] = temp
			}
		}
	}

	fmt.Printf("Array after sorting: \n")
	for i := 0; i <= 4; i++ {
		fmt.Printf("%d ", arr[i])
	}
}

Output:

Enter array elements:
Elements: arr[0]: 12
Elements: arr[1]: 34
Elements: arr[2]: 5
Elements: arr[3]: 11
Elements: arr[4]: 3
Array after sorting:
3 5 11 12 34

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 and also created a variable temp.

fmt.Printf("Enter array elements: \n")
for i:=0;i<=4;i++{
    fmt.Printf("Elements: arr[%d]: ",i)
    fmt.Scanf("%d",&arr[i])
}

In the above code, we read array elements from the user.

for i:=0; i<=4; i++{
        for j:=4;j>=i+1;j--{
            if(arr[j]<arr[j-1]){
                temp=arr[j]
                arr[j]=arr[j-1]
                arr[j-1]=temp
            }
        }
    }

In the above code, we applied bubble sort to arrange array elements in ascending order, Here In each phase of bubble sort highest element get moved to the last After that we printed the sorted array on the console screen.
