help plz~~~~~~storing a matrix in C

if i have a matrix like

A B C D E .... Z

A 0.1 0.12 0.5 0.04 ...

B 0.33 0.2 0.11 0.14

C 0.9 0.02 ..............
.
.
.
Z

-------------------------------
where the entries in the maxtrix are the probability converting column to row
eg probabilty column A -> row C = 0.33

cos there are 26x26 entries....
my Q is ...what's an easy way to store these probabilities in C , so i can find the
corresponding prob say Z -> E ..etc


thanks for the help

Code:

---

int  main(void)
{
      float data[26][26] = {
                                    {0.1, 0.2, 0.3, /* ... */},
                                    {0.4, 0.5, 0.6}
                                    /*  ...  */
                                };

      printf(" AxB: %f\n", data['A' - 65]['B' - 65]);

      return (0);
}
