我需要使用Dr.Memory检查数组索引是否超出范围。在这种情况下，我不使用动态内存分配。
当我用Dr.Memory检查此代码时。我使用的是Windows 11。

int main() {
    clock_t start, end;
    float cpu_time_used;
    start = clock();

    int array[5] = {2, 4, 5, 6, 7};
    int number = array[10];
    printf("This is a number: %i\n", number);

    end = clock();
    cpu_time_used = ((float) (end - start)) / CLOCKS_PER_SEC;
    printf("\nTotal speed  was %f\n", cpu_time_used);

    return EXIT_SUCCESS;
}

我从Dr.Memory得到这个输出。正如你所看到的，没有抱怨索引超出范围。为什么？
