1.for循环中提高性能

void process_data(int *data, int size) {
    int i;
    for (i = 0; i < size - 3; i += 4) {
        data[i] = data[i] * 2;
        data[i + 1] = data[i + 1] * 2;
        data[i + 2] = data[i + 2] * 2;
        data[i + 3] = data[i + 3] * 2;
    }
    // 处理剩余的元素
    for (; i < size; i++) {
        data[i] = data[i] * 2;
    }
}
