structure - C 中的嵌套数组结构

Question

下面是它给我和我的代码的错误:

workspace.c: 在函数“main”中:

workspace.c:38: 错误:下标值既不是数组也不是指针

workspace.c:39: 错误:下标值既不是数组也不是指针

任何输入将不胜感激!谢谢你的时间。

查看此代码:Tested with no error

#define n 4
struct process
{
    struct segment{

        struct page
        {
            int pid;
            int p[4];
        }pages[n];
    }segments[n];
}processes[3];


int main()
{
    int a, b, c;
    int k = 0;
     for(a = 0; a < 3; a++)
     {
        for(b = 0; b < 4; b++)
        {
            for(c = 0; c < 4; c++)
            {
                k++;
                processes[a].segments[b].pages[c].pid = k;
                printf("Segment: %d, Page: %d, PID: %d\n",a,b,processes[a].segments[b].pages[c].pid);
            }
        }

     }

    return 0;
}
