Array using recursion
Download as DOCX, PDF0 likes88 views
This program uses recursion to print the elements of an array. It takes in the array, number of elements, and initial index as parameters for the recursive function. The function prints the element at the current index, increments the index, and calls itself until the index equals the number of elements, at which point it returns without printing or recursing further.
