c 语言 求数组中偶数的和

有两种方法：
一是判别偶数：

#include 

int main() {

    int numbers[] = {10, 13, 6, 7, 4};;
    int sum = 0;
    int index;
    
    for (index = 0; index < 5; index++) {
        if (numbers[index]%2 == 0){
            sum += numbers[index];
        }
    }
    
    printf("The sum is %dn", sum);
    
    return 0;
}

二是判别奇数：

#include 


int main() {

    int numbers[] = {10, 13, 6, 7, 4};
    int sum = 0;
    int index;

    for (index = 0; index < 5; index++) {
        if (numbers[index]%2 != 0){
            continue;
        }
        sum += numbers[index];
    }

    printf("The sum is %dn", sum);

    return 0;
}
