Multi-dimensional arrays

Ok, Im close to finishing my project and the last problem is to enable Logging.

The project is menu based and the user selects from 5 options and does different stuff. Fine.

However, the logging requirements are to Display the option, the Count of times it has been accessed & the Order its been accessed.

And the Order only stores the last 10 option calls

The example is

OPTION        COUNT         ORDER
    1                  1                  1
    2                  0
    3                  3                   3,4
    4                  10                 2,5,6,7,8,10
    5                  0
    6                  1                   9




So you can from that example, that the user has been using option 4 alot - 10 times & the order has recorded only the last 6 - as it stores only the last 10 option calls.

Hope that explains the problem.


My solution was to have a double array

int sessionLog[6][2] = {{0,0},{0,0},{0,0},{0,0},{0,0},{0,0}};

So the first element would hold the total Count that option has been used and the second is the Order it was accessed. Both could be incremented as needed.


Then *crunch*

I realized that thats fine if each option is only accessed *once*.

So that's my question I need some help with - how could it store multiple accesses? A triple array??

Or what about an array of arrays?

Any ideas?

How about an array of structs

struct info {
      int option;
      int count;
      int order[10];
}

struct info mydata[6];

This should solve your problem ...

You can ofcourse use a linked list for order[]
