Looping a fixed size array without defining its size in C

Question

Some example code to start the question:

 #define FOO_COUNT 5

 static const char *foo[] = {
       "123",
       "456",
       "789",
       "987",
       "654"
 };

The way this would normally be iterated over, as for one example, is the following:

int i = FOO_COUNT;
while (--i >= 0) {
 printf("%s\n", foo[i]);

Is there anyway to do the above without explicitly having the human count the number 5? In the future I might add/remove elements and forget to update the size of the array, thus breaking my app.

Answer 1

int i = sizeof(foo)/sizeof(foo[0]);
