Question

how to check if an numeric array is empty in c ??
i have int arr[10];
and i have to check if this is empty or not , what should i do ?

Answer 1

Wouldn't you have an index that would be zero if nothing was in there? Do you initialize the elements to an impossible value, then you could check them all for that value.

Answer 2

if (strcmp(arr, "") == 0)
or
if(arr[0] == '\0') {}
