# Take array
n = int(input("Enter array size: "))
arr = []
for i in range(n):
    arr.append(int(input(f"Element {i+1}: ")))

# Sum odd elements
sum_odd = 0
for element in arr:
    if element % 2 != 0:
        sum_odd += element

print(f"Sum of odd elements: {sum_odd}")

Output

Enter array size: 5
Element 1: 2
Element 2: 3
Element 3: 4
Element 4: 5
Element 5: 6
Sum of odd elements: 8

Filter odd elements and sum.

Key Concepts:

  • Check if element is odd
  • Add to sum if odd
  • Conditional accumulation
