How to write Jagged array into shared memory with C/C++

Question

I have the following jagged array (rank 6) which is output of a C/C++ code (this is achieved by splitting a rectangular 2D array)

I need to write it into the shared memory.

A rectangular 2D array is written into the shared memory as follows

    int MemoryID = 1;
    int dimension[2]={60,11};
    SHMID = shmget(MemoryID, sizeof(int)*dimension[0]*dimension[1], 0666 | IPC_CREAT);
    if(SHMID == -1) 
    {
        std::cerr << "Error creating shared memory segment" << std::endl;
        return -1;
    }

    int rows = dimension[0];
    int cols= dimension[1];
    int (*arr)[cols];
    arr = (int(*)[cols]) shmat(SHMID, NULL, 0);  

Now arr can be accessed like this

    for(int i=0;i<rows;i++)
    {
        for(int j=0;j<cols;j++)
        {
            arr[i][j];
        }
    }

Can anyone let me know how to write the code (to store the above mention 6D jagged array into the shared memory) in C/C++?
