The elements of an integer -valued array can be set to 0 (i.e., the array can be cleared) recursively as follows: An array of size 0 is already cleared; Otherwise, set the first element of the array to 0, and clear the rest of the array Write a void function named clear that accepts an integer array, and the number of elements in the array and sets the elements of the array to 0.
LANGUAGE: C++
CHALLENGE:
The elements of an integer -valued array can be set to 0 (i.e., the array can be cleared) recursively as follows: An array of size 0 is already cleared; Otherwise, set the first element of the array to 0, and clear the rest of the array Write a void function named clear that accepts an integer array, and the number of elements in the array and sets the elements of the array to 0.
SOLUTION:
void clear(int *array, int length){ if (length == 0)return; array[0] = 0; clear(array + 1, length-1); }
