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

# Count
even = 0
odd = 0

for element in arr:
    if element % 2 == 0:
        even += 1
    else:
        odd += 1

print(f"Even: {even}, Odd: {odd}")

Output

Enter array size: 5
Element 1: 2
Element 2: 3
Element 3: 4
Element 4: 5
Element 5: 6
Even: 3, Odd: 2

Check each element for even/odd.

Key Concepts:

Use modulo to check even/odd
Increment respective counter
Print counts

Count Positive, Negative, Zero
