Print Sum of Even Numbers

Code

#include <stdio.h>

int sum_even_numbers(int *ptr, int n) {
    // Your logic here
    // int sum = 0;
    // for(int i=0; i<n; i++){
    //     if(*(ptr+i)%2==0){
    //         sum += *(ptr+i);
    //     }
    // }
    // return sum;
    int *end = ptr + n, sum=0;
    while(ptr<end){
        if(*ptr % 2 == 0){
            sum += *ptr;
        }
        ptr ++;
    }
    return sum;
}

int main() {
    int n;
    scanf("%d", &n);

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int result = sum_even_numbers(arr, n);

    printf("Sum = %d", result);

    return 0;
}
