In this program, we need to print the element which is present on even position. Even positioned element can be found by traversing the array and incrementing the value of i by 2.

In the above array, elements on even position are b and d.

ALGORITHM:

  • STEP 1: Declare and initialize an array.
  • STEP 2: Calculate the length of the declared array.
  • STEP 3: Loop through the array by initializing the value of variable "i" to 1 (because first even positioned element lies on i = 1) then incrementing its value by 2, i.e., i=i+2.
  • STEP 4: Print the elements present in even positions.

#Initialize array     
arr = [1, 2, 3, 4, 5];     
     
print("Elements of given array present on even position: ");    
#Loop through the array by incrementing the value of i by 2    
    
#Here, i will start from 1 as first even positioned element is present at position 1.    
for i in range(1, len(arr), 2):    
    print(arr[i]);

 

Output:

Elements of given array present on even position:
2
4
