Q. Program to sort the elements of an array in ascending order.

Explanation

In this program, we need to sort the given array in ascending order such that elements will be arranged from smallest to largest. This can be achieved through two loops. The outer loop will select an element, and inner loop allows us to compare selected element with rest of the elements.

Original array:

Array after sorting:

Program to sort the elements of an array in ascending order

Elements will be sort in such a way that smallest element will appear on extreme left which in this case is 1. The largest element will appear on extreme right which in this case is 8.

Algorithm

  1. Declare and initialize an array.
  2. Loop through the array and select an element.
  3. The inner loop will be used to compare the selected element from the outer loop with the rest of the elements of the array.
  4. If any element is less than the selected element then swap the values.
  5. Continue this process till entire array is sorted in ascending order.

Solution

Python

#Initialize array 
arr = [5, 2, 8, 7, 1]; 
temp = 0;
 
#Displaying elements of original array
print("Elements of original array: ");
for i in range(0, len(arr)):
    print(arr[i], end=" ");
 
#Sort the array in ascending order
for i in range(0, len(arr)):
    for j in range(i+1, len(arr)):
        if(arr[i] > arr[j]):
            temp = arr[i];
            arr[i] = arr[j];
            arr[j] = temp;
 
print();
 
#Displaying elements of the array after sorting

print("Elements of array sorted in ascending order: ");
for i in range(0, len(arr)):
    print(arr[i], end=" ");

Output:

Elements of original array: 
5 2 8 7 1 
Elements of array sorted in ascending order: 
1 2 5 7 8

C

#include 
 
int main()
{
    //Initialize array 
    int arr[] = {5, 2, 8, 7, 1}; 
    int temp = 0;
    
    //Calculate length of array arr
    int length = sizeof(arr)/sizeof(arr[0]);
    
    //Displaying elements of original array
    printf("Elements of original array: \n");
    for (int i = 0; i < length; i++) { 
        printf("%d ", arr[i]); 
    }  
    
    //Sort the array in ascending order
    for (int i = 0; i < length; i++) { 
        for (int j = i+1; j < length; j++) { 
           if(arr[i] > arr[j]) {
               temp = arr[i];
               arr[i] = arr[j];
               arr[j] = temp;
           } 
        } 
    }
    
    printf("\n");
    
    //Displaying elements of array after sorting
    printf("Elements of array sorted in ascending order: \n");
    for (int i = 0; i < length; i++) { 
        printf("%d ", arr[i]);
    }
    return 0;
}

Output:

Elements of original array: 
5 2 8 7 1 
Elements of array sorted in ascending order: 
1 2 5 7 8

JAVA

public class SortAsc {
    public static void main(String[] args) {    
        
        //Initialize array 
        int [] arr = new int [] {5, 2, 8, 7, 1}; 
        int temp = 0;
        
        //Displaying elements of original array
        System.out.println("Elements of original array: ");
        for (int i = 0; i < arr.length; i++) { 
            System.out.print(arr[i] + " ");
        }
        
        //Sort the array in ascending order
        for (int i = 0; i < arr.length; i++) { 
            for (int j = i+1; j < arr.length; j++) { 
               if(arr[i] > arr[j]) {
                   temp = arr[i];
                   arr[i] = arr[j];
                   arr[j] = temp;
               } 
            } 
        }
      
        System.out.println();
        
        //Displaying elements of array after sorting
        System.out.println("Elements of array sorted in ascending order: ");
        for (int i = 0; i < arr.length; i++) { 
            System.out.print(arr[i] + " ");
        }
    }
