How can I count an array element in C?

Question

I make a DFA Simulator.

if Node 0 is initial state and Node 3 is final state, like weight graph implementation.

char CurrentStateAccept[stateN][alphabetN][alphabetN] = { {"01"} , {"0"} , {"0","1"} ,{} }; // 0, 1, 2, 3
int NextState[stateN][alphabetN] = {{1},{2},{0,3},{}};

I want to get 1, 1, 2, 0

node 0, accept(0 or 1) -> node 1
node 1, accept(0) -> node 2
node 2, accept(0) -> node 0
node 2, accept(1) -> node 3
and node 3 is final state of dfa.

so I want to get char CurrentStateAccept[each state]'s element number for using 'for loop' ex)

for(i=0; i<currentState element num; i++)
{
   for(j=0; j<end of alphabet of each element; j++)
   {
       there is acceptable state? or not?
   }
}

How can I get in C?

you mean something like this

sizeof(array)/sizeof(type of array);

Or, even easier: (sizeof array / sizeof array[0])
