Count even and odd elements in array using function Program Code

#include <stdio.h>

int countEven(int arr[], int size) {
    int count = 0;
    for(int i = 0; i < size; i++) {
        if(arr[i] % 2 == 0) {
            count++;
        }
    }
    return count;
}

int countOdd(int arr[], int size) {
    int count = 0;
    for(int i = 0; i < size; i++) {
        if(arr[i] % 2 != 0) {
            count++;
        }
    }
    return count;
}

int main() {
    int nums[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    int n = sizeof(nums) / sizeof(nums[0]);
    
    int evenCount = countEven(nums, n);
    int oddCount = countOdd(nums, n);
    
    printf("Even numbers: %d\n", evenCount);
    printf("Odd numbers: %d\n", oddCount);
    return 0;
}
