array

I have an array like this:

int a[100];

I am filling only the first 4 elements in this array:

a[0] = 1;
a[1] = 2;
a[2] = 3;
a[3] = 4;

When I do sizeof(a)/sizeof(a[0]) it returns 100.

Is there a way I can get number of elements to which I have assinged a value and thus filtering out the remaining 96 unassigned elements?

thanks
