Ruby program to sort an array in ascending order using bubble sort

Last Updated : December 15, 2025

Problem Solution

In this program, we will create an array of integers and then we will sort the created array in ascending order using bubble sort.

Program/Source Code

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

# Ruby program to sort an array in ascending order 
# using bubble Sort

arr = [12,69,49,87,68];

i=0;

while (i < 5)
  j = 4;
  while (j > i) 
    if (arr[j] < arr[j - 1]) 
      t = arr[j];
      arr[j] = arr[j - 1];
      arr[j - 1] = t;
    end
    j = j - 1
  end
  i = i + 1
end

print "Sorted Array: \n";
i=0;

while(i<5)
    print arr[i]," ";
    i=i+1;
end

Output

Sorted Array: 
12 49 68 69 87 

Explanation

In the above program, we created an array of integer elements. Then we sorted the array elements in ascending order using the bubble sort mechanism. After that, we printed the sorted array.
