numbers[0] = 10;
numbers[1] = 20;
numbers[2] = 30;
numbers[3] = 40;
numbers[4] = 50;

c
int numbers[] = {10, 20, 30, 40, 50};

c
#include 
int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    int sum = 0;
    int i;
    for (i = 0; i < 5; i++) {
        sum += numbers[i];
    }
    printf("数组元素的和为：%d\n", sum);
    return 0;
