Thread: Counting # of elements in array or file.

The following will only work on arrays where the last element is a null character.

Code:

int countArray(char *array){
    int n = 0;
    while(array[n] != '\0')
        n++;

    return n;
}

However, in a well designed system you should always know the size of your arrays, be it by defining a constant to set the base size or keeping a counter for a dynamic array. That number - 1 would be the actual length of the array.
