Structure of a Recursive Program
Explore how recursive functions work by breaking down problems into smaller subproblems and applying base cases to stop recursion. Learn to write correct recursive C++ programs that avoid memory errors and use recursion effectively to create concise, logical code.
Basic syntax #
Let’s go over the basic syntax of the recursive function.
The recursive function consists of the following two parts:
-
if: represents the base case when the function should stop calling itself. It simply returns the result to the calling point.
-
else: represents the recursive case when the function calls itself repetitively until it reaches a base case.
Illustration
The recursive function keeps calling itself in a nested manner until it encounters a base condition. When the base condition is reached, it continues returning the value to the calling function until the original calling function is reached.
